Mouse IL-2 ELISA Kit(Plus)

Detection Principle:

This kit uses double antibody sandwich ELISA technology. Specific anti mouse il-2  Capture antibody was pre coated on a high affinity microplate. Add the standard, the sample to be tested and the biotin labeled detection antibody into the wells of the enzyme plate in turn, shake well and mix well, and then place it at room temperature for 2 hours of incubation process; Il-2  Bound to solid-phase antibody and detection antibody. After washing sufficiently to remove free and unbound components, streptavidin HRP (sa-hrp) labeled with horseradish peroxidase was added. After washing again, TMB chromogenic substrate was added and incubated at room temperature in the dark to develop color. The depth of color response and sample   The concentration of IL-2 was positively correlated. Add stop solution to stop the reaction, and use a microplate reader to measure the absorbance value at 450 nm detection wavelength (correction wavelength 570-630 nm).

Background:

Interleukin 2 (IL-2) is a 15 kDa glycoprotein. In humans, it is encoded by a single gene located in the q26 – 28 region of chromosome 4. It is a class of signaling molecules in the immune system, regulating the immune function of white blood cells (leukocytes, usually lymphocytes)Activity of. IL-2 is the body's natural response to microbial infection, distinguishing foreign and self antigens. IL-2 functions by interacting with the IL-2 receptor, which is composed of three chains, namely α Chain (CD25), β Chain (CD122) and γ Chain (CD132).

Monitoring the IL-2 content in serum provides a more detailed perspective for a variety of pathological conditions, including cancer, infectious diseases, transplant rejection, multiple sclerosis, rheumatoid arthritis, systemic lupus erythematosus and type I diabetes.
