Take out the microplate from the sealed bag that has been equilibrated to room temperature. Please put the unused slats back into the aluminum foil bag and re-seal; \u003cbr\u003e3. Add to the microplate 300uL Washing liquid, let stand and soak 30 Seconds, discard the lotion and pat the microplate dry on absorbent paper. Please use it immediately and do not let the microplate dry; \u003cbr\u003e4. Add different concentration standards, experimental samples or quality control articles into the corresponding wells, and each well 100uL 。 Seal the reaction wells with plate sealing tape and incubate at room temperature 2 hour ;\u003cbr\u003e5. The liquid in the plate is sucked off and the plate is washed using a washing bottle, a multi-channel plate washer or an automatic plate washer. Washing solution per well 300uL Then the wash liquid in the plate is aspirated off. Repeat Operation 3 Times. Trying to absorb the residual liquid as much as possible every time you wash the plate will help to get good experimental results. At the end of the last plate washing, please suck all the liquid in the plate or turn the plate upside down, and pat all the residual liquid dry on absorbent paper; \u003cbr\u003e6. Within each well added 100uL Detect antibodies. Seal the reaction wells with plate sealing tape and incubate at room temperature 2 Hour; \u003cbr\u003e7.

Repeat th 5 Step washing operation; \u003cbr\u003e10. Within each well added 100uL Chromogenic solution, incubate at room temperature 5-30 Minutes, pay attention to avoiding light; \u003cbr\u003e11. Within each well added 50uL Stop solution, the color of the solution in the well will change from blue to yellow. If the color of the solution changes to green or the color changes are inconsistent, pat the microplate gently to mix the solution evenly; \u003cbr\u003e12. After addition of stop solution 30 Within minutes, measured using a plate reader 450nm Absorbance value, set 540nm Or 570nm As the correction wavelength. If dual-wavelength correction is not used, the accuracy of the results may be affected; \u003cbr\u003e13. Calculation results: Add the corrected absorbance values of each standard and sample (OD450-OD540 Or OD570) , average of repeated well readings and then subtract the average zero standard OD Value. Four-parameter logic using computer software (4-PL) Curve fitting creates a standard curve. Another way is to plot the standard concentration and make the logarithm with the corresponding OD The values were logarithmic to generate a curve, and the best fit line was determined by regression analysis. This process can generate a data fit that is sufficiently useful but less accurate. If the sample is diluted, the concentration should be calculated by multiplying the dilution factor. \u003cbr\u003e\u003cdiv\u003e\u003cimg style=\"display: block; margin-left: auto; margin-right: auto;\" src=\"https:\/\/absin.oss-cn-shanghai.aliyuncs.com\/absin-china\/20241114\/e2e4d02a892946e48b8be03b5a091360.jpg\" alt=\"\" width=\"369\" height=\"286\"\u003e\u003c\/div\u003e\n\u003cstrong\u003e Note: \u003c\/strong\u003e The standard curve data provided is for reference only, and the sample content should be calculated according to the standard curve drawn in the same test. \u003cbr\u003e\u003cbr\u003e\u003cstrong\u003e 3.

Standard curves were created by 4-parameter logic (4-PL) curve fitting using computer software. Alternatively, a curve can be generated by plotting the logarithm of the concentration of the standard against the logarithm of the corresponding OD value, and the best fit line can be determined by regression analysis. This process produces an adequate but less accurate fit to the data. If the sample is diluted, the concentration should be multiplied by the dilution.\u003cstrong\u003e\u003cstrong\u003e\u003cbr\u003e\u003c\/strong\u003e\u003c\/strong\u003e\u003cdiv\u003e\u003cimg style=\"display: block; margin-left: auto; margin-right: auto;\" src=\"https:\/\/absin.oss-cn-shanghai.aliyuncs.com\/absin-china\/20240201\/84b805a141c641e18449b8ec36ac948f.jpg\" alt=\"\" width=\"301\" height=\"235\"\u003e\u003c\/div\u003e\n\u003cstrong\u003eNote: The standard curve data provided in \u003c\/strong\u003eare for reference only, and the sample content should be calculated according to the standard curve drawn in the same test.\u003cstrong\u003e\u003cstrong\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003e3.

Mouse IL-2 precursor is a 169-amino acid (AA) peptide containing a 20-amino acid signal sequence and a 149-amino acid mature chain. There is an additional potential site for O-linked glycosylation, as well as a polyglutamine region at residues 35 to 46. It is worth noting that mouse IL-2 has multiple alleles, resulting in differences in the number of glutamine at amino acids 21-46 and the number of TSSS repeats in the mouse IL-2 sequence (SwissProt#:P04351). The amino acid sequence of mature mouse IL-2 shared 56% and 73% identity with human and rat IL-2, respectively, with the major difference located in the polyglutamine region. There is some cross-reactivity between mouse and human IL-2. Functionally, IL-2 was originally recognized as a T-cell growth factor and, therefore, was used in the treatment of cancer and AIDS patients, as well as to enhance the immune response. However, these efforts have had limited effect. \"Experimental studies have shown that mice lacking IL-2 or its receptor also develop lymphoproliferation and autoimmune diseases, suggesting that IL-2 is a growth-limiting rather than growth-inducing factor.\" Recent studies have shown that the real cause of lymphocyte proliferation is the inability to produce CD4+FoxP3+CD25\/IL-2Rα+Treg cells. It is important to note that now IL - 2 is considered successful induction of CD8 + memory cells necessary for memory response. It is well known that mammalian cells expressing IL-2 include CD4+ and CD8+T cells, NK cells, NKT cells, and dendritic cells. The IL-2 receptor is complex and consists of three different subunits. The two subunits can be combined with ligands, called IL - 2 r alpha and beta IL - 2 r. IL-2Rα is 55kDa and binds IL-2 with low affinity. IL - 2 beta for 75 kda, is part of the IL - 15 receptors, moderate affinity with IL - 2. Signal transduction is mediated by IL-2Rβ and a 64kDa common γ chain (γc). Gamma c and IL - 4, 7, 9, 15-21 and Shared receptors. Signal transducerγc does not bind to IL-2 but heterodimerizes with IL-2Rβ to form a functional IL-2 receptor.

The precursor of mouse IL-4 is 140 amino acids, including a 20-amino acid signal peptide and a 120-amino acid mature chain. IL-4 contains three N-linked glycosylation potential sites, three intra-chain disulphide bonds, and its structure is a bundled tetra-α-spirochetes. Similar to human IL-4, mouse IL-4 has a small selective splicer. \"Unlike human IL-4, the expression of this spliceosome is thought to be low and of little significance.\" The amino acid sequence of mature mouse IL-4 shared 43% and 63% identity with human and rat IL-4, respectively. Studies have shown that the activities of human, mouse and rat IL-4 are species specific. IL - 4 by toward Th2 CD4 + T cells, basophils and mast cells and NKT cells, gamma delta T cells with eosinophilic cells expressed. \u003cbr\u003eIL - 4 has played a key role in type 2 immune reaction, can promote the Th2 differentiation and B cell secretory immunoglobulin G1 and immunoglobulin E subtypes. IL-4 causes Th2 differentiation by binding to type I or type II receptor complexes containing IL-4 receptor alpha subunits coupled to the γ chain or IL13Rα1, respectively. IL - 4 by cell surface receptors of different dimers, activate JAK family of protein complex amino acid kinase, cause its cytoplasm C phosphorylation. This triggers the recruitment and phosphorylation of STAT6. The phosphorylation and conformational changes of STAT6 lead to dimerization, nuclear translocation, binding and transcriptional activation of STAT6 target genes, including IL-4, IL-5, IL-13, and Th2-specific cytokines GATA3 and c-Maf. On the function, IL - 4 B cell proliferation, survival, and promote mice immune globulin class into IgG1 and IgE, promote the mast cells, eosinophils, and basophils start and chemokines, promote Th2 phenotype naive CD4 + cells, and promote the epithelial cell proliferation and activation. IL-4 is also an important cytokine in tumor immunology. In early experiments in mice, the researchers found that IL-4 had potent anti-tumor abilities. Mice reject tumors expressing IL-4 and develop long-term antitumor immunity. This may be due to the antiangiogenic effect of IL-4 or its ability to activate, select for CD8+T cells. \"Paradoxically, emerging evidence suggests that IL-4 is a tumor-promoting molecule, and therefore, IL-4 is a reverse-acting cytokine.\" \"A possible explanation is that IL-4 induces upregulation of antiapoptotic molecules in tumor cells and downregulation of cytolytic molecules in CD8+T cells.\" In addition, tumor-produced IL-4 is also thought to act on local tumor-associated macrophages (TAMs) to induce the secretion of cathepsins that promote cell migration.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eGeneral Notes\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1.

It plays an important role in the acute phase of disease response, inflammation, hematopoiesis, bone metabolism and cancer progression. Mature mouse IL-6 has 187 amino acids and is 42% and 85% identical to human and rat IL-6, respectively. Alternative splicing within IL-6 results in a variety of isoforms, some of which exhibit antagonistic properties. Expression of IL - 6 cells is known, \"These include CD8+T cells, fibroblasts, synoviocytes, adipocytes, osteoblasts, megakaryocytes, endothelial cells (under the influence of endothelin), sympathetic neurons, cerebral cortical neurons, adrenal medullary chromaffin cells, retinal pigment cells, mast cells, keratinocytes, Langerhans cells, fetal and adult astrocytes, and neutrophils. , monocytes, eosinophils, colon epithelial cells, B1B cells and islet beta cells. The production of IL - 6 is usually in the sugar cortical hormone, catecholamine and under the control of secondary sexual steroids, generally associated with cell activation. The level of IL-6 in normal human blood is in the range of 1pg\/mL. It is slightly increased in the menstrual period, moderately increased in the middle and late stage of some cancers, and significantly increased after major surgery. \u003cbr\u003eIL-6 elicits cell signaling through a cell surface receptor, which is a heterodimeric complex consisting of a ligand-binding subunit (the IL-6 receptor) and a signal transduction subunit gp130. IL-6 binds to the IL-6 receptor, triggering the binding of IL-6 receptor to gp130 and the dimerization of gp130. gp130 is also a component of the receptors for CLC, CNTF, CT-1, IL-11, IL-27, LIF, and OSM. Soluble IL - 6 receptor is produced by alternative splicing and protease cutting. \"Through a trans-signaling mechanism, the combination of soluble IL-6 and IL-6 receptor triggers a response in cells that lack the IL-6 receptor on the surface but express gp130.\" Expression of the IL-6 receptor is largely restricted to hepatocytes, monocytes, lymphocytes, and resting lymphocytes, and since the gp130 molecule is expressed very broadly, trans-signaling enables a broader range of cell types to respond to IL-6. \"Soluble gp130 spliceosome prevented IL-6\/IL-6R trans-signaling, but not signaling by other cytokines using gp130 as a co-receptor.\" \u003cbr\u003eThe acute inflammatory response induced by IL-6, together with tumor necrosis factor-α (TNF-α) and IL-1, plays an almost unique role in fever and acute liver inflammation. It also plays an important role in the transformation from acute inflammation to acquired immunity or chronic inflammatory diseases. IL-6 dysregulation can promote chronic inflammation, such as obesity, insulin resistance, inflammatory bowel disease, inflammatory arthritis, and sepsis, often involving IL-6 trans-signaling. In the presence of transforming growth factor TGF-β, IL-6 plays an important role in the differentiation of Th17 inflammatory cells from naive T cells. IL-6 regulates bone resorption by promoting the activity of Th17 inflammatory cells, which is the main factor causing inflammatory joint damage in rheumatoid arthritis. IL-6 is involved in the formation and destabilization of atherosclerotic plaques. However, IL-6 also has anti-inflammatory effects, such as secretion of IL-6 by skeletal muscle during physical exercise, promoting hematopoiesis as a growth factor for hematopoietic stem cells, inducing the maturation of B cells into plasma cells, and immortalization of multiple myeloma cells. Also promote IL - 6, but may not start the other inflammation associated with cancer, such as colitis associated cancer.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eGeneral Notes\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1.

IL-10 is mainly secreted by monocytes, while lymphocytes, type II helper T cells (Th2), mast cells, cd4+cd25+foxp3+ regulatory T cells, and partially activated T cells and B cells secrete less. It has multiple effects on immune regulation and inflammation. It downregulates Th1 cytokines, MHC class II antigens and costimulatory molecules of macrophages. It can also enhance B cell survival, proliferation and antibody secretion. IL-10 can block NF - \u0026amp; kappa; B activity, and participate in JAK-STAT signaling pathway regulation.

Standard curves were created by 4-parameter logic (4-PL) curve fitting using computer software. Alternatively, a curve can be generated by plotting the logarithm of the concentration of the standard against the logarithm of the corresponding OD value, and the best fit line can be determined by regression analysis. This process produces an adequate but less accurate fit to the data.

Vascular endothelial growth factor is PDGF family, the family proteins there are eight characteristics of conservative and cystine nodes through a reverse parallel disulfide bond dimers (4). After selective splicing, VEGF spliceosome has different amino acid lengths. VEGF120, VEGF164, VEGF188 in mice; Human VEGF VEGF121, VEGF145, VEGF164, VEGF183, VEGF189 and VEGF206. VEGF165 was the most expressed and active isoform in human, followed by VEGF121 and VEGF89. The same may be true of mice. With the exception of VEGF120 and VEGF121, the other isoforms of VEGF contain the basic heparin-binding domain and do not diffuse freely. Mice VEGF164 and corresponding protein amino acid 97% homology of rats; The homology with human or porcine VEGF was 89%, with bovine VEGF 88%, and with cat, horse, and dog VEGF 90%. VEGF is expressed in a variety of cells and tissues, including skeletal muscle and cardiomyocytes, hepatocytes, osteoblasts, neutrophils, macrophages, keratinocytes, brown adipocytes, CD34+ stem cells, endothelial cells, cellulose cells, vascular smooth muscle cells, and so on. VEGF expression is induced by hypoxia and cytokines, including IL-1, IL-6, IL-8, oncostatinM and tumor necrosis factor-α. Expression of VEGF isoforms also varies during development and in adults. \"The dimer of \u003cbr\u003eVEGF binds to two related tyrosine kinase receptors, VEGFR1 (also called FLt-1) and VEGFR2 (Flk-1\/KDR).\" Binding of VEGF to its receptor induces homodimerization and autophosphorylation of the latter. These receptors possess seven extracellular immunoglobulin-like domains. Vascular endothelial cells and some non-endothelial cells have VEGF receptor expression. \"Although VEGF has the highest affinity for VEGFR1, VEGFR2 is the major factor regulating the angiogenic activity of VEGF.\" VEGF165 also binds to the semaphoring receptor and neuropilin-1, thereby promoting the complex formation with VEGFR2. \u003cbr\u003eVEGF is famous for its participation in angiogenesis. During embryonic development, VEGF regulates the proliferation, migration and survival of endothelial cells, thereby regulating the density and volume of blood vessels, but it does not play a role in the pattern of blood vessel formation. VEGF promotes bone formation through the recruitment of osteoblasts and chondrocytes, and it is also a monocyte chemotactic factor. In the postpartum period, VEGF maintains the integrity of vascular endothelial cells and is a potent mitogen for large\/small vascular endothelial cells. In adults, VEGF plays a role mainly in wound repair and in the female reproductive cycle. In disease tissues, VEGF promote the permeability of blood vessels. Thus, VEGF is involved in the metastatic process of tumors by promoting extravasation and tumor angiogenesis. Various therapeutic strategies aimed at blocking VEGF activity are being used to control VEGF-induced tumor angiogenesis.

The main function of IgE is to produce immunity to parasites, such as worms, Schistosoma mansoni, Trichinella spiralis and Fasciola hepatica. IgE plays a key role in type I hypersensitivity reactions, such as allergic asthma, most sinusitis, allergic rhinitis, food allergy, chronic urticaria and atopic dermatitis. IgE also plays an important role in the response to allergens, such as allergens, bee stings, antigens used in desensitization immunotherapy. Although IgE content is the least (IgE content in normal human serum only accounts for 0.05% of all Ig classes), it can trigger the strongest inflammatory response. The content of IgE in the blood of patients with hereditary allergy is 10 times higher than that of normal people. In a variety of autoimmune diseases, such as systemic lupus erythematosus (SLE), rheumatoid arthritis (RA) and psoriasis, the level of IgE has increased.

Standard curves were created by 4-parameter logic (4-PL) curve fitting using computer software. Alternatively, a curve can be generated by plotting the logarithm of the concentration of the standard against the logarithm of the corresponding OD value, and the best fit line can be determined by regression analysis. This process produces an adequate but less accurate fit to the data.

IL-1α and IL-1β bind to the same cell surface receptor and share biological functions. \"With the exception of skin keratinocytes, some epithelial cells, and certain cells of the central nervous system, unstimulated cells from healthy mice do not produce IL-1.\" \"However, in response to inflammatory agents, infections, or microbial endotoxins, IL-1 is produced in large quantities by macrophages and a variety of other cells.\" IL-1β plays a key role in the physiological processes of immune response and inflammation, bone remodeling, fever, glucose metabolism, growth hormone \/IGF-1. \"Abnormal or sustained production of IL-1 has been associated with a range of pathological conditions, including sepsis, rheumatoid arthritis, inflammatory bowel disease, acute and chronic myeloid leukemia, insulin-dependent diabetes mellitus, atherosclerosis, nerve injury, and aging-related diseases.\" \u003cbr\u003eIL-1α and IL-1β have structurally related peptides that share approximately 25% identity at the amino acid level. They were synthesized as the size of 31 kDa precursor, and then cracking into mature protein, molecular weight is about 17.5 kDa. Caspase 1 \/ ICEI cracking IL - 1 beta precursor is a key step in the inflammatory response. Neither IL-1α nor IL-1β contain typical hydrophobic signal peptides, but there is evidence that these factors can be secreted through nonclassical pathways. Part of raw IL - 1 alpha can appear on the cell membrane, and may have biological activities. Unlike precursor IL - 1 alpha, beta IL - 1 precursor compared with mature body almost do not have biological activities. Both unprocessed and mature IL-1β can be exported from the cell. \u003cbr\u003eIL - 1 alpha and beta IL - 1 with IL - 1 ra combination immunoglobulin superfamily receptors play a role. \"Cells expressing the 80-kda transmembrane type I receptor (IL-1RI) include T cells, fibroblasts, keratinocytes, endothelial cells, synovial fluid lining cells, chondrocytes, and hepatocytes.\" \"Cells expressing the 68kDa transmembrane type II receptor (IL-1RII) include B cells, neutrophils, and bone marrow cells.\" \"The two IL-1 receptors share approximately 28% identity in their extracellular domains, but a significant difference is found in their intracellular domains: the type II receptor has an intracellular domain of only 29 amino acids, whereas the type I receptor has an intracellular domain of 217 amino acids.\" IL-1RII does not produce a signal for IL-1 and may act as a decoy receptor to attenuate IL-1 function. IL-1 receptor accessory protein (IL-1RAcP) is associated with IL-1RI and required for IL-1RI signal transduction. IL-1ra is a secretory molecule that acts as a competitive inhibitor of IL-1.

IL - 12 by 35 kda (p35) and 40 kda (p40) of two subunits, the two subunits by disulfide bond is linked together, no amino acid sequence homology between each other. The mature p35 subunit is 196 amino acids long, containing seven cysteines and a potential N-linked glycosylation site. Mature mouse p35 shares 63% and 86% amino acid identity with human and rat, respectively. Mature mice p40 subunits long 313 amino acids, including 13 cysteine and five potential glycosylation sites of N - connection. Some studies have reported that the p40 sequence is polymorphic, but this IL-12 p70 kit does not recognize these allelic products. \u003cbr\u003emature mouse p40 has 72% and 93% amino acid identity with human and rat, respectively. Although p35 resembles a ligand for erythropoietin, p40 is more similar to the N-terminus of the erythropoietin receptor, with WSXWS domains, an immunoglobulin-like domain, and four conserved cysteines. This suggests that IL-12 may be a cytokine receptor mimetic, similar to the IL-6\/ soluble IL-6R complex. It is worth noting that the p40 can exist in the form of monomer or homologous dimers, but never found p35 monomer form. p40 is the larger of the two subunits of interleukin 23 (IL-23). Although IL-12 has long been considered a secretory molecule, membrane-bound IL-12 has also been found in human and mouse cells. Il-12-producing cells include macrophages, dendritic cells, monocytes, Langerhans cells, neutrophils, keratinocytes, plasmacytoid dendritic cells, microglia, CD8+DC (mouse cells only), and non-germinal center (CD38-CD44+) B cells (human cells only). The high-affinity receptor for \u003cbr\u003emouse IL-12 is composed of at least two type I transmembrane glycoproteins, similar to members of the cytokine receptor superfamily. Beta 1 first subunits (R) of 100 kda, with Kd = 1 nm and IL - 12. This receptor is the primary binding site for the p40 subunit; The second subunit (Rβ2) is 130kDa and has no amino acid homology with the Rβ1 subunit. The receptor is an important part of signal transduction, as a disulfide bond connected p30 - p40 dimers attachment points. As mentioned above, mouse p40 exists as a monomeric, dimeric form, and binds either at p35 to form IL-12 or at p19 to form IL-23. Both homodimer p40 and IL-23 can bind IL-12R and act as antagonists that do not transmit signals. Alternatively, p40 homodimer can also bind to Rβ1 and activate microglia and macrophages. Functionally, IL-12 has been shown to enhance cytotoxicity and induce interferon-γ production by NK cells, T cells, and dendritic epidermal T cells. It has been reported that IL-12 can induce the production of interferon-γ by macrophages. Together with its IL-12 family members such as IL-23 and IL-27, IL-12 can promote the progression of CD4+ Th1-type immune responses. In response to infection, IL-27 is secreted first to promote the excess of TH0 to THR0\/1, followed by IL-12 secretion to generate Th1 effector cells. \"Production together with IL-18 and IL-12 transforms effector cells into Th1 memory cells, which are then activated by IL-23.\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eGeneral Notes\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1.

IFN-γ plays a key role in the host defense process through its antiviral, antiproliferative and immunomodulatory functions. \"In many cell types, IFN-γ induces cytokine production and upregulates the expression of a variety of membrane proteins, including types I and II major histocompatibility complex (MHC) antigens, Fc receptors, leukocyte adhesion molecules, and B7 family antigens.\" IFN-γ is a potent activator of macrophage response. It directs the synthesis, conversion, and secretion of immunoglobulin by B cells. IFN-γ affects the development of T helper cell phenotype by inhibiting the differentiation of Th2 cells and stimulating the development of Th1 cells. IFN-γ plays an important role in the progression of autoimmune diseases and inflammatory diseases such as atherosclerosis. \u003cbr\u003ebioactive IFN - gamma is made up of two non covalently linked with different degree of glycosylation of 20 to 25 kda homologous dimer composed of subunits. Mature mouse IFN-γ shared 86% amino acid sequence identity with rat IFN-γ, and 38-44% amino acid sequence identity with bovine, dog, cotton rat, horse, cat, human, pig and rhesus monkey IFN-γ. The IFN-γ dimers assemble before the transmembrane IFN-γRI(α subunit) and then bind to the transmembrane IFN-γRII(β subunit), thus forming an active receptor complex containing two α and β subunits. IFN-γRII in the receptor complex increases ligand affinity as well as the efficiency of signal transduction. Although the α chain is widely expressed in a variety of cell types, the receptor β chain is associated with the state of IFN-γ response and its expression is tightly regulated. \u003cbr\u003eUnder inflammatory conditions, IFN-γ can be produced by a variety of cell types, including dendritic epidermal \/γδT cells, keratinocytes, peripheral γδT cells, mast cells, neurons, CD8+T cells, macrophages, B cells, neutrophils, natural killer cells, CD4+T cells, and testicular spermatids.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eGeneral Notes\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1.

Calculation results: Add the corrected absorbance values of each standard and sample (OD450-OD540 Or OD570) , average of repeated well readings and then subtract the average zero standard OD Value. Using computer software for four-parameter logic (4-PL) Curve fitting creates a standard curve. Another way is to plot the standard concentration and make the logarithm with the corresponding OD The values were logarithmic to generate a curve, and the best fit line was determined by regression analysis. This process can generate a data fit that is sufficiently useful but less accurate.

It is a pleiotropic factor that plays a central role in inflammatory response, immune system development, apoptosis and lipid metabolism. TNF-α is also involved in many pathological processes, including asthma, Crohn's disease, rheumatoid arthritis, neuropathic pain, obesity, type II diabetes, septic shock, autoimmunity, and cancer. Human TNF-α is a 26kDa type II transmembrane protein consisting of a 35 amino acid (aa) intracellular domain, a 21aa transmembrane segment, and a 177aa extracellular domain (ECD). In the ECD region, human TNF-α has 97% amino acid sequence homology with macaque monkey, and 71-92% amino acid sequence homology with cattle, dog, cotton rat, horse, cat, mouse, pig and rat. It can be expressed by a variety of different cells such as immune cells, epithelial cells, endothelial cells, tumor cells. TNF-α can induce lysis of tumor cells and virus-infected cells, and binds to soluble TNFRI to generate transmembrane transfer signals of downstream cells. TACE\/ADAM17 can cause the shedding of TNF-α-containing cell membrane to release active TNF-α cytokine. It is a trimer composed of TNF-α extracellular soluble structure with a molecular weight of 55 kDa.\u003cbr\u003eTNF-α has two receptors: TNFRI and TNFRII. TNFRI has a molecular weight of 55-60kDa and is widely expressed; TNFRII has a molecular weight of 78-80 kDa and is limited to hematopoietic cell expression. Both are expressed as homotrimers; TNF-α and TNFRI and TNFRII bind with similar affinities and can promote the activation of NFκB. However, only TNFRI has a cell death domain, which can trigger apoptosis. Both soluble receptors are released into human serum and urine and can neutralize the activity of TNF-α.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eGeneral Notes\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1.

It promotes B cell activation, immunoglobulin class switching to IgE and upregulation of CD23\/Fc epsilon RII. IL-13 signals through a receptor complex containing IL-13 R alpha1 and IL-4 R alpha. The compound is used as a type 2 receptor IL - 4. IL-13 ralpha2 binds IL-13 and prevents IL-13 from signaling through the IL-13R alpha1\/IL-4 Ralpha complex. Il-13-bound IL-13 R alpha2 can directly promote tumor cell invasion and tissue fibrosis development.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eGeneral Notes\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1.

RANTES, which regulates the expression and secretion of normal T cells, is a member of the CC subfamily of chemotactic cytokines, also known as CCL5. The protein has a wide range of sources, most of which are expressed in the inflammatory factor IL-1 \u0026amp; amp; Beta; Or tnf-\u0026amp; Alpha; CCL5 can be released under the stimulation of. Generally, CCL5 is mainly secreted by cd8+t cells, epithelial cells, fibroblasts and platelets.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eCCL5, like other chemotactic cytokines, can bind to its specific receptors in monomeric or multimeric form. CCL5 has a dimeric structural basis, forming multimers at high concentrations, and often exists as monomers after endocytosis. Glycosaminoglycans (GAGs) on the cell surface can lead to the multimerization of CCL5. Multimerized CCL5 can not only activate inflammatory cells, prolong and aggravate inflammatory responses, but also regulate cell growth and differentiation. When CCL5 is monomeric or dimeric or its concentration is nanomolar, its receptors are CCR1, CCR3, CCR4 and CCR5, which have chemotactic activity, can enhance cytotoxicity and inhibit HIV replication.

Then dilute to the following concentrations: 200 pg\/mL, 100 pg\/mL, 50 pg\/mL, 25 pg\/mL, 12.5 pg\/mL, 6.25 pg\/mL, 3.125 pg\/mL, and 0 pg\/mL. Serial dilution method: Take seven EP tubes and add 500uL of universal diluent to each. Pipette 500uL of the 200pg\/mL standard working solution into the first EP tube and mix thoroughly to make a 100pg\/mL standard working solution. Repeat this procedure for subsequent tubes. The last tube serves as a blank well; there is no need to pipette liquid from the penultimate tube. See the figure below for details.\u003cbr\u003e3. Preparation of biotinylated detection antibody working solution: Centrifuge the concentrated biotinylated antibody at 1000×g for 1 minute 15 minutes before use. Dilute the 100× concentrated biotinylated antibody to a 1× working concentration with universal diluent (e.g., 10uL concentrate + 990uL universal diluent). Prepare and use immediately.\u003cbr\u003e4. Prepare the enzyme conjugate working solution: 15 minutes before use, centrifuge the 100× concentrated enzyme conjugate at 1000×g for 1 minute. Dilute the 100× concentrated HRP enzyme conjugate to a 1× working concentration with universal diluent (e.g., 10 μL of concentrate + 990 μL of universal diluent). Prepare immediately.\u003cbr\u003e5. Prepare the 1× wash solution: Dispense 10 mL of 20× wash solution into 190 mL of distilled water (concentrated wash solution removed from the refrigerator may crystallize; this is normal. Allow to stand at room temperature until the crystals have completely dissolved before preparing).\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eProcedure:\u003c\/strong\u003e\u003cbr\u003e1. Remove the desired strips from the aluminum foil bag after equilibration at room temperature for 10 minutes. Seal the remaining strips in a ziplock bag and return to 4°C.\u003cbr\u003e2. Sample addition: Add 100 μL of sample or standard of varying concentrations to the corresponding wells. Add 100 μL of universal diluent to the blank wells. Cover with a film and incubate at 37°C for 60 minutes. (Recommendation: Dilute the sample to be tested at least 1-fold with universal diluent before adding it to the ELISA plate. This will reduce the impact of matrix effects on the test results. The sample concentration should be multiplied by the corresponding dilution factor when calculating the final sample concentration. It is recommended to run replicates for all test samples and standards.)\u003cbr\u003e3. Add Biotinylated Antibody: Remove the ELISA plate and discard the liquid without washing. Add 100 μL of Biotinylated Antibody Working Solution directly to each well. Cover with a film and incubate at 37°C for 60 minutes.\u003cbr\u003e4. Wash: Discard the liquid and add 300 μL of 1x Wash Solution to each well. Let stand for 1 minute, shake off the wash solution, and pat dry on absorbent paper. Repeat this process three times (a plate washer can also be used).\u003cbr\u003e5. Add Enzyme Conjugate Working Solution: Add 100 μL of Enzyme Conjugate Working Solution to each well. Cover with a film and incubate at 37°C for 30 minutes.\u003cbr\u003e6. Washing: Discard the liquid and wash the plate five times as in step 4.\u003cbr\u003e7. Adding substrate: Add 90 μL of substrate (TMB) to each well, cover with a sealing film, and incubate at 37°C in the dark for 15 minutes.\u003cbr\u003e8. Adding stop solution: Remove the ELISA plate and add 50 μL of stop solution directly to each well. Immediately measure the OD value of each well at a wavelength of 450 nm.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eCalculating experimental results:\u003c\/strong\u003e\u003cbr\u003e1.

Plot the standard curve of the four-parameter logistic function on double-logarithmic graph paper, with concentration as the horizontal axis and OD value as the vertical axis.\u003cbr\u003e2. If the sample OD value is higher than the upper limit of the standard curve, dilute the sample appropriately and retest.

It is glial-specific and primarily expressed by astrocytes, but not all astrocytes express S100B. Studies have shown that S100B is expressed only by a subset of mature astrocytes surrounding blood vessels and by NG2-expressing cells. This protein may play a role in neuronal elongation, melanoma cell proliferation, stimulation of Ca2+ flux, inhibition of PKC-mediated phosphorylation, astrocytosis, axonal proliferation, and inhibition of microtubule assembly.

Pipette 500uL of the 200pg\/mL standard working solution into the first EP tube and mix thoroughly to make a 100pg\/mL standard working solution. Repeat this procedure for subsequent tubes. The last tube serves as a blank well; there is no need to pipette liquid from the penultimate tube. See the figure below for details.\u003cbr\u003e3. Preparation of biotinylated detection antibody working solution: Centrifuge the concentrated biotinylated antibody at 1000×g for 1 minute 15 minutes before use. Dilute the 100× concentrated biotinylated antibody to a 1× working concentration with universal diluent (e.g., 10uL concentrate + 990uL universal diluent). Prepare and use immediately.\u003cbr\u003e4. Prepare the enzyme conjugate working solution: 15 minutes before use, centrifuge the 100× concentrated enzyme conjugate at 1000×g for 1 minute. Dilute the 100× concentrated HRP enzyme conjugate to a 1× working concentration with universal diluent (e.g., 10 μL of concentrate + 990 μL of universal diluent). Prepare immediately.\u003cbr\u003e5. Prepare the 1× wash solution: Dispense 10 mL of 20× wash solution into 190 mL of distilled water (concentrated wash solution removed from the refrigerator may crystallize; this is normal. Allow to stand at room temperature until the crystals have completely dissolved before preparing).\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eProcedure:\u003c\/strong\u003e\u003cbr\u003e1. Remove the desired strips from the aluminum foil bag after equilibration at room temperature for 10 minutes. Seal the remaining strips in a ziplock bag and return to 4°C.\u003cbr\u003e2. Sample addition: Add 100 μL of sample or standard of varying concentrations to the corresponding wells. Add 100 μL of universal diluent to the blank wells. Cover with a film and incubate at 37°C for 60 minutes. (Recommendation: Dilute the sample to be tested at least 1-fold with universal diluent before adding it to the ELISA plate. This will reduce the impact of matrix effects on the test results. The sample concentration should be multiplied by the corresponding dilution factor when calculating the final sample concentration. It is recommended to run replicates for all test samples and standards.)\u003cbr\u003e3. Add Biotinylated Antibody: Remove the ELISA plate and discard the liquid without washing. Add 100 μL of Biotinylated Antibody Working Solution directly to each well. Cover with a film and incubate at 37°C for 60 minutes.\u003cbr\u003e4. Wash: Discard the liquid and add 300 μL of 1x Wash Solution to each well. Let stand for 1 minute, shake off the wash solution, and pat dry on absorbent paper. Repeat this process three times (a plate washer can also be used).\u003cbr\u003e5. Add Enzyme Conjugate Working Solution: Add 100 μL of Enzyme Conjugate Working Solution to each well. Cover with a film and incubate at 37°C for 30 minutes.\u003cbr\u003e6. Washing: Discard the liquid and wash the plate five times as in step 4.\u003cbr\u003e7. Adding substrate: Add 90 μL of substrate (TMB) to each well, cover with a sealing film, and incubate at 37°C in the dark for 15 minutes.\u003cbr\u003e8. Adding stop solution: Remove the ELISA plate and add 50 μL of stop solution directly to each well. Immediately measure the OD value of each well at a wavelength of 450 nm.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eCalculating experimental results:\u003c\/strong\u003e\u003cbr\u003e1.

After incubation and washing, the sample is developed using the substrate TMB. TMB is converted to blue by HRP peroxidase and then to yellow by acid. The intensity of the color is positively correlated with the Klotho (KL) content in the sample.

Dilute the 100× concentrated biotinylated antibody to a 1× working concentration with universal diluent (e.g., 10uL concentrate + 990uL universal diluent). Prepare and use immediately.\u003cbr\u003e\u003cbr\u003e4. Prepare the enzyme conjugate working solution: 15 minutes before use, centrifuge the 100× concentrated enzyme conjugate at 1000×g for 1 minute. Dilute the 100× concentrated HRP enzyme conjugate to a 1× working concentration with universal diluent (e.g., 10 μL of concentrate + 990 μL of universal diluent). Prepare immediately.\u003cbr\u003e\u003cbr\u003e5. Prepare the 1× wash solution: Dispense 10 mL of 20× wash solution into 190 mL of distilled water (concentrated wash solution removed from the refrigerator may crystallize; this is normal. Allow to stand at room temperature until the crystals have completely dissolved before preparing).\u003cbr\u003e\u003cbr\u003eProcedure:\u003cbr\u003e1. Remove the desired strips from the aluminum foil bag after equilibration at room temperature for 10 minutes. Seal the remaining strips in a ziplock bag and return to 4°C.\u003cbr\u003e\u003cbr\u003e2. Sample addition: Add 100 μL of sample or standard of varying concentrations to the corresponding wells. Add 100 μL of universal diluent to the blank wells. Cover with a film and incubate at 37°C for 60 minutes. (Recommendation: Dilute the sample to be tested at least 1-fold with universal diluent before adding it to the ELISA plate. This will reduce the impact of matrix effects on the test results. The sample concentration should be multiplied by the corresponding dilution factor when calculating the final sample concentration. It is recommended to run replicates for all test samples and standards.)\u003cbr\u003e\u003cbr\u003e3. Add Biotinylated Antibody: Remove the ELISA plate and discard the liquid without washing. Add 100 μL of Biotinylated Antibody Working Solution directly to each well. Cover with a film and incubate at 37°C for 60 minutes.\u003cbr\u003e\u003cbr\u003e4. Wash: Discard the liquid and add 300 μL of 1x Wash Solution to each well. Let stand for 1 minute, shake off the wash solution, and pat dry on absorbent paper. Repeat this process three times (a plate washer can also be used).\u003cbr\u003e\u003cbr\u003e5. Add Enzyme Conjugate Working Solution: Add 100 μL of Enzyme Conjugate Working Solution to each well. Cover with a film and incubate at 37°C for 30 minutes.\u003cbr\u003e\u003cbr\u003e6. Washing: Discard the liquid and wash the plate five times as in step 4.\u003cbr\u003e\u003cbr\u003e7. Adding substrate: Add 90 μL of substrate (TMB) to each well, cover with a sealing film, and incubate at 37°C in the dark for 15 minutes.\u003cbr\u003e\u003cbr\u003e8. Adding stop solution: Remove the ELISA plate and add 50 μL of stop solution directly to each well. Immediately measure the OD value of each well at a wavelength of 450 nm.\u003cbr\u003e\u003cbr\u003eCalculating experimental results:\u003cbr\u003e1. Calculate the average OD value of the standard and sample replicates and subtract the OD value of the blank well as a correction factor. Plot the standard curve of the four-parameter logistic function on double-logarithmic graph paper, with concentration as the horizontal axis and OD value as the vertical axis.\u003cbr\u003e\u003cbr\u003e2. If the sample OD value is higher than the upper limit of the standard curve, dilute the sample appropriately and retest.

Sample, standard, biotin-labeled detection antibody, and HRP conjugate are sequentially added to microwells pre-coated with a collagen type II (COLⅡ) capture antibody. After incubation and washing, the sample is developed using the substrate TMB. TMB converts to blue under the catalysis of HRP and to yellow under the action of acid. The intensity of the color is positively correlated with the amount of collagen type II (COLⅡ) in the sample. The absorbance (OD value) is measured at 450 nm using a microplate reader to calculate the sample concentration.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSource\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMouse\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSynonym\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMouse COLⅡ ELISA Kit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDetection Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDouble antibody sandwich method\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eComposition\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003ctable style=\"border-collapse: collapse;

The last tube serves as a blank well; there is no need to pipette liquid from the penultimate tube. See the figure below for details.\u003cbr\u003e3. Preparation of biotinylated detection antibody working solution: Centrifuge the concentrated biotinylated antibody at 1000×g for 1 minute 15 minutes before use. Dilute the 100× concentrated biotinylated antibody to a 1× working concentration with universal diluent (e.g., 10uL concentrate + 990uL universal diluent). Prepare and use immediately.\u003cbr\u003e4. Prepare the enzyme conjugate working solution: 15 minutes before use, centrifuge the 100× concentrated enzyme conjugate at 1000×g for 1 minute. Dilute the 100× concentrated HRP enzyme conjugate to a 1× working concentration with universal diluent (e.g., 10 μL of concentrate + 990 μL of universal diluent). Prepare immediately.\u003cbr\u003e5. Prepare the 1× wash solution: Dispense 10 mL of 20× wash solution into 190 mL of distilled water (concentrated wash solution removed from the refrigerator may crystallize; this is normal. Allow to stand at room temperature until the crystals have completely dissolved before preparing).\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eProcedure:\u003c\/strong\u003e\u003cbr\u003e1. Remove the desired strips from the aluminum foil bag after equilibration at room temperature for 10 minutes. Seal the remaining strips in a ziplock bag and return to 4°C.\u003cbr\u003e2. Sample addition: Add 100 μL of sample or standard of varying concentrations to the corresponding wells. Add 100 μL of universal diluent to the blank wells. Cover with a film and incubate at 37°C for 60 minutes. (Recommendation: Dilute the sample to be tested at least 1-fold with universal diluent before adding it to the ELISA plate. This will reduce the impact of matrix effects on the test results. The sample concentration should be multiplied by the corresponding dilution factor when calculating the final sample concentration. It is recommended to run replicates for all test samples and standards.)\u003cbr\u003e3. Add Biotinylated Antibody: Remove the ELISA plate and discard the liquid without washing. Add 100 μL of Biotinylated Antibody Working Solution directly to each well. Cover with a film and incubate at 37°C for 60 minutes.\u003cbr\u003e4. Wash: Discard the liquid and add 300 μL of 1x Wash Solution to each well. Let stand for 1 minute, shake off the wash solution, and pat dry on absorbent paper. Repeat this process three times (a plate washer can also be used).\u003cbr\u003e5. Add Enzyme Conjugate Working Solution: Add 100 μL of Enzyme Conjugate Working Solution to each well. Cover with a film and incubate at 37°C for 30 minutes.\u003cbr\u003e6. Washing: Discard the liquid and wash the plate five times as in step 4.\u003cbr\u003e7. Adding substrate: Add 90 μL of substrate (TMB) to each well, cover with a sealing film, and incubate at 37°C in the dark for 15 minutes.\u003cbr\u003e8. Adding stop solution: Remove the ELISA plate and add 50 μL of stop solution directly to each well. Immediately measure the OD value of each well at a wavelength of 450 nm.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eCalculating experimental results:\u003c\/strong\u003e\u003cbr\u003e1.

Plot the standard curve of the four-parameter logistic function on double-logarithmic graph paper, with concentration as the horizontal axis and OD value as the vertical axis.\u003cbr\u003e2. If the sample OD value is higher than the upper limit of the standard curve, dilute the sample appropriately and retest.

Pipette 500uL of the 200ng\/mL standard working solution into the first EP tube and mix thoroughly to make a 100ng\/mL standard working solution. Repeat this procedure for subsequent tubes. The last tube serves as a blank well; there is no need to pipette liquid from the penultimate tube. See the figure below for details.\u003cbr\u003e3. Preparation of biotinylated detection antibody working solution: Centrifuge the concentrated biotinylated antibody at 1000×g for 1 minute 15 minutes before use. Dilute the 100× concentrated biotinylated antibody to a 1× working concentration with universal diluent (e.g., 10uL concentrate + 990uL universal diluent). Prepare and use immediately.\u003cbr\u003e4. Prepare the enzyme conjugate working solution: 15 minutes before use, centrifuge the 100× concentrated enzyme conjugate at 1000×g for 1 minute. Dilute the 100× concentrated HRP enzyme conjugate to a 1× working concentration with universal diluent (e.g., 10 μL of concentrate + 990 μL of universal diluent). Prepare immediately.\u003cbr\u003e5. Prepare the 1× wash solution: Dispense 10 mL of 20× wash solution into 190 mL of distilled water (concentrated wash solution removed from the refrigerator may crystallize; this is normal. Allow to stand at room temperature until the crystals have completely dissolved before preparing).\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eProcedure:\u003c\/strong\u003e\u003cbr\u003e1. Remove the desired strips from the aluminum foil bag after equilibration at room temperature for 10 minutes. Seal the remaining strips in a ziplock bag and return to 4°C.\u003cbr\u003e2. Sample addition: Add 100 μL of sample or standard of varying concentrations to the corresponding wells. Add 100 μL of universal diluent to the blank wells. Cover with a film and incubate at 37°C for 60 minutes.\u003cbr\u003e(Recommendation: Dilute the sample to be tested at least 1-fold with universal diluent before adding it to the ELISA plate. This will reduce the impact of matrix effects on the test results. The sample concentration should be multiplied by the corresponding dilution factor when calculating the final sample concentration. It is recommended to run replicates for all test samples and standards.)\u003cbr\u003e3. Add Biotinylated Antibody: Remove the ELISA plate and discard the liquid without washing. Add 100 μL of Biotinylated Antibody Working Solution directly to each well. Cover with a film and incubate at 37°C for 60 minutes.\u003cbr\u003e4. Wash: Discard the liquid and add 300 μL of 1x Wash Solution to each well. Let stand for 1 minute, shake off the wash solution, and pat dry on absorbent paper. Repeat this process three times (a plate washer can also be used).\u003cbr\u003e5. Add Enzyme Conjugate Working Solution: Add 100 μL of Enzyme Conjugate Working Solution to each well. Cover with a film and incubate at 37°C for 30 minutes.\u003cbr\u003e6. Washing: Discard the liquid and wash the plate five times as in step 4.\u003cbr\u003e7. Adding substrate: Add 90 μL of substrate (TMB) to each well, cover with a sealing film, and incubate at 37°C in the dark for 15 minutes.\u003cbr\u003e8. Adding stop solution: Remove the ELISA plate and add 50 μL of stop solution directly to each well. Immediately measure the OD value of each well at a wavelength of 450 nm.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eCalculating experimental results:\u003c\/strong\u003e\u003cbr\u003e1.

Plot the standard curve of the four-parameter logistic function on double-logarithmic graph paper, with concentration as the horizontal axis and OD value as the vertical axis.\u003cbr\u003e2. If the sample OD value is higher than the upper limit of the standard curve, dilute the sample appropriately and retest.

Sample, standard, biotin-labeled detection antibody, and HRP enzyme conjugate are sequentially added to microwells pre-coated with adiponectin receptor 1 (ADIPOR1) capture antibody. After incubation and washing, the sample is developed using the substrate TMB. TMB is converted to blue by peroxidase (HRP) catalysis and to yellow by acid. The intensity of the color is positively correlated with the amount of Adiponectin receptor 1 (ADIPOR1) in the sample.

It is a member of the progesterone and adipokinase receptor (PAQR) family and is also known as PAQR1. Similar to G protein-coupled receptors (GPCRs), AdipoR1 possesses seven transmembrane domains. However, AdipoR1 is oriented on the membrane in the opposite direction to GPCRs (i.e., cytoplasmic N-terminus, extracellular C-terminus) and does not bind to G proteins. Adiponectin receptors AdipoR1 and AdipoR2 act as receptors for globular and full-length adiponectin, mediating increased activity of AMPK and PPAR-α ligands, as well as fatty acid oxidation and glucose uptake by adiponectin.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eGeneral Notes\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1.

Remove the test kit from the refrigerator 10 minutes in advance and equilibrate to room temperature.\u003cbr\u003e2. Prepare the standard gradient working solution: Add 1 mL of universal diluent to the lyophilized standard, let it stand for 15 minutes to completely dissolve, then gently mix (concentration is 200 ng\/mL). Then dilute to the following concentrations: 200 ng\/mL, 100 ng\/mL, 50 ng\/mL, 25 ng\/mL, 12.5 ng\/mL, 6.25 ng\/mL, 3.125 ng\/mL, and 0 ng\/mL. Serial dilution method: Take seven EP tubes and add 500uL of universal diluent to each. Pipette 500uL of the 200ng\/mL standard working solution into the first EP tube and mix thoroughly to make a 100ng\/mL standard working solution. Repeat this procedure for subsequent tubes. The last tube serves as a blank well; there is no need to pipette liquid from the penultimate tube. See the figure below for details.\u003cbr\u003e3. Preparation of biotinylated detection antibody working solution: Centrifuge the concentrated biotinylated antibody at 1000×g for 1 minute 15 minutes before use. Dilute the 100× concentrated biotinylated antibody to a 1× working concentration with universal diluent (e.g., 10uL concentrate + 990uL universal diluent). Prepare and use immediately.\u003cbr\u003e4. Prepare the enzyme conjugate working solution: 15 minutes before use, centrifuge the 100× concentrated enzyme conjugate at 1000×g for 1 minute. Dilute the 100× concentrated HRP enzyme conjugate to a 1× working concentration with universal diluent (e.g., 10 μL of concentrate + 990 μL of universal diluent). Prepare immediately.\u003cbr\u003e5. Prepare the 1× wash solution: Dispense 10 mL of 20× wash solution into 190 mL of distilled water (concentrated wash solution removed from the refrigerator may crystallize; this is normal. Allow to stand at room temperature until the crystals have completely dissolved before preparing).\u003cbr\u003e\u003cbr\u003eProcedure:\u003cbr\u003e1. Remove the desired strips from the aluminum foil bag after equilibration at room temperature for 10 minutes. Seal the remaining strips in a ziplock bag and return to 4°C.\u003cbr\u003e2. Sample addition: Add 100 μL of sample or standard of varying concentrations to the corresponding wells. Add 100 μL of universal diluent to the blank wells. Cover with a film and incubate at 37°C for 60 minutes. (Recommendation: Dilute the sample to be tested at least 1-fold with universal diluent before adding it to the ELISA plate. This will reduce the impact of matrix effects on the test results. The sample concentration should be multiplied by the corresponding dilution factor when calculating the final sample concentration. It is recommended to run replicates for all test samples and standards.)\u003cbr\u003e3. Add Biotinylated Antibody: Remove the ELISA plate and discard the liquid without washing. Add 100 μL of Biotinylated Antibody Working Solution directly to each well. Cover with a film and incubate at 37°C for 60 minutes.\u003cbr\u003e4. Wash: Discard the liquid and add 300 μL of 1x Wash Solution to each well. Let stand for 1 minute, shake off the wash solution, and pat dry on absorbent paper. Repeat this process three times (a plate washer can also be used).\u003cbr\u003e5. Add Enzyme Conjugate Working Solution: Add 100 μL of Enzyme Conjugate Working Solution to each well. Cover with a film and incubate at 37°C for 30 minutes.\u003cbr\u003e6. Washing: Discard the liquid and wash the plate five times as in step 4.\u003cbr\u003e7. Adding substrate: Add 90 μL of substrate (TMB) to each well, cover with a sealing film, and incubate at 37°C in the dark for 15 minutes.\u003cbr\u003e8. Adding stop solution: Remove the ELISA plate and add 50 μL of stop solution directly to each well. Immediately measure the OD value of each well at a wavelength of 450 nm.\u003cbr\u003e\u003cbr\u003eCalculating experimental results:\u003cbr\u003e1. Calculate the average OD value of the standard and sample replicates and subtract the OD value of the blank well as a correction factor. Plot the standard curve of the four-parameter logistic function on double-logarithmic graph paper, with concentration as the horizontal axis and OD value as the vertical axis.\u003cbr\u003e2. If the sample OD value is higher than the upper limit of the standard curve, dilute the sample appropriately and retest. Multiply the sample concentration by the corresponding dilution factor.\u003cbr\u003e\u003cbr\u003e\u003cimg style=\"page-break-inside: avoid; display: block; margin-left: auto; margin-right: auto;\" src=\"https:\/\/absin.oss-cn-shanghai.aliyuncs.com\/absin_new_bak-china\/20250312\/f91fe200f4404a7999ae198defe322cd.png\" alt=\"\" width=\"512\" height=\"356\"\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTheory \u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eThis kit uses a double-antibody sandwich enzyme-linked immunosorbent assay (ELISA). Sample, standard, biotin-labeled detection antibody, and HRP enzyme conjugate are sequentially added to microwells pre-coated with fetuin B (FETUB) capture antibodies. After incubation and washing, the sample is developed using the substrate TMB. TMB converts to blue under the catalysis of HRP and to yellow under the action of acid. The intensity of the color is positively correlated with the amount of fetuin B (FETUB) in the sample. The absorbance (OD value) is measured at 450 nm using a microplate reader to calculate the sample concentration.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSource\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMouse\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSynonym\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMouse Fetuin B ELISA Kit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDetection Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDouble antibody sandwich method\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eComposition\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003ctable style=\"border-collapse: collapse;

Serial dilution method: Take seven EP tubes and add 500uL of universal diluent to each. Pipette 500uL of the 200ng\/mL standard working solution into the first EP tube and mix thoroughly to make a 100ng\/mL standard working solution. Repeat this procedure for subsequent tubes. The last tube serves as a blank well; there is no need to pipette liquid from the penultimate tube. See the figure below for details.\u003cbr\u003e3. Preparation of biotinylated detection antibody working solution: Centrifuge the concentrated biotinylated antibody at 1000×g for 1 minute 15 minutes before use. Dilute the 100× concentrated biotinylated antibody to a 1× working concentration with universal diluent (e.g., 10uL concentrate + 990uL universal diluent). Prepare and use immediately.\u003cbr\u003e4. Prepare the enzyme conjugate working solution: 15 minutes before use, centrifuge the 100× concentrated enzyme conjugate at 1000×g for 1 minute. Dilute the 100× concentrated HRP enzyme conjugate to a 1× working concentration with universal diluent (e.g., 10 μL of concentrate + 990 μL of universal diluent). Prepare immediately.\u003cbr\u003e5. Prepare the 1× wash solution: Dispense 10 mL of 20× wash solution into 190 mL of distilled water (concentrated wash solution removed from the refrigerator may crystallize; this is normal. Allow to stand at room temperature until the crystals have completely dissolved before preparing).\u003cbr\u003e\u003cbr\u003eProcedure:\u003cbr\u003e1. Remove the desired strips from the aluminum foil bag after equilibration at room temperature for 10 minutes. Seal the remaining strips in a ziplock bag and return to 4°C.\u003cbr\u003e2. Sample addition: Add 100 μL of sample or standard of varying concentrations to the corresponding wells. Add 100 μL of universal diluent to the blank wells. Cover with a film and incubate at 37°C for 60 minutes. (Recommendation: Dilute the sample to be tested at least 1-fold with universal diluent before adding it to the ELISA plate. This will reduce the impact of matrix effects on the test results. The sample concentration should be multiplied by the corresponding dilution factor when calculating the final sample concentration. It is recommended to run replicates for all test samples and standards.)\u003cbr\u003e3. Add Biotinylated Antibody: Remove the ELISA plate and discard the liquid without washing. Add 100 μL of Biotinylated Antibody Working Solution directly to each well. Cover with a film and incubate at 37°C for 60 minutes.\u003cbr\u003e4. Wash: Discard the liquid and add 300 μL of 1x Wash Solution to each well. Let stand for 1 minute, shake off the wash solution, and pat dry on absorbent paper. Repeat this process three times (a plate washer can also be used).\u003cbr\u003e5. Add Enzyme Conjugate Working Solution: Add 100 μL of Enzyme Conjugate Working Solution to each well. Cover with a film and incubate at 37°C for 30 minutes.\u003cbr\u003e6. Washing: Discard the liquid and wash the plate five times as in step 4.\u003cbr\u003e7. Adding substrate: Add 90 μL of substrate (TMB) to each well, cover with a sealing film, and incubate at 37°C in the dark for 15 minutes.\u003cbr\u003e8. Adding stop solution: Remove the ELISA plate and add 50 μL of stop solution directly to each well. Immediately measure the OD value of each well at a wavelength of 450 nm.\u003cbr\u003e\u003cbr\u003eCalculating experimental results:\u003cbr\u003e1. Calculate the average OD value of the standard and sample replicates and subtract the OD value of the blank well as a correction factor. Plot the standard curve of the four-parameter logistic function on double-logarithmic graph paper, with concentration as the horizontal axis and OD value as the vertical axis.\u003cbr\u003e2. If the sample OD value is higher than the upper limit of the standard curve, dilute the sample appropriately and retest. Multiply the sample concentration by the corresponding dilution factor.\u003cbr\u003e\u003cbr\u003e\u003cimg style=\"page-break-inside: avoid; display: block; margin-left: auto; margin-right: auto;\" src=\"https:\/\/absin.oss-cn-shanghai.aliyuncs.com\/absin_new_bak-china\/20250312\/eedd1eee06094267a4d2b421c55cf765.png\" alt=\"\" width=\"512\" height=\"356\"\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTheory \u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eThis kit uses a double-antibody sandwich enzyme-linked immunosorbent assay (ELISA). Sample, standard, biotin-labeled detection antibody, and HRP conjugate are sequentially added to microwells pre-coated with a pre-collagen type III (PC III) capture antibody. After incubation and washing, the sample is developed using the substrate TMB. TMB is converted to blue by HRP peroxidase and to yellow by acid. The intensity of the color is positively correlated with the amount of pre-collagen type III (PC III) in the sample. The absorbance (OD) is measured at 450 nm using a microplate reader to calculate the sample concentration.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSource\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMouse\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSynonym\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMouse Pre-collagen type iii ELISA Kit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDetection Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDouble antibody sandwich method\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eComposition\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003ctable style=\"border-collapse: collapse;
