Background
The Cytometric Bead Array (CBA) technology enables the capture of soluble analytes or analyte panels using beads with known sizes and fluorescence intensities, thereby allowing the detection of analytes via flow cytometry.
Each capture bead in the CBA kit is conjugated with a specific antibody. The detection reagent provided with the kit is Streptavidin-Phycoerythrin, and the intensity of the fluorescent signal generated by this reagent is proportional to the amount of bound analyte.
When the capture beads and detection reagent are incubated together with the test sample containing target analytes, sandwich complexes are formed. Detection of these complexes by flow cytometry allows for the identification of particles exhibiting the fluorescence characteristics of both the beads and the detection reagent.

Distribution Diagram
The figure shows the distribution of microsphere clusters corresponding to different cytokines; it enables the simultaneous differentiation of multiple cytokines, providing a basis for the group definition for the subsequent quantitative analysis of each cytokine.
Distribution Diagram
The histogram reflects the number of particles in each microsphere group.

Example of IL-2,IL-4,IL-5,IL-6,IL-10,IFN-γ,MCP-1 standard curve in Assay Diluent .
Quantifiction of Monkey PBMC
PBMC Unsimulated Supernatant: The cells of PBMCs were cultured for24 hours, the cell culture supernatant was collected and analyzed quantitatively using S0Q1002.
PBMC simulated Supernatant: The cells of PBMCs were stimulated with 10 μg/mL PMA. After 24 hours, the cell culture supernatant was collected and analyzed quantitatively using S0Q1002.
Linearity
After serial dilution of the high-concentration combined proteins of monkey IL-2, IL-4, IL-5, IL-6, IL-10, IFN-γ, MCP-1 using plasma, serum, and cell culture supernatant matrices respectively, the concentrations of Monkey IL-2, IL-4, IL-5, IL-6, IL-10, IFN-γ, MCP-1 were measured and interpolated from the target standard curves and corrected for sample dilution.
Intra-assay precision
Ten replicates of each of three different levels of IL-2, IL-4, IL-5, IL-6, IL-10, IFN-γ and MCP-1 were tested.
Inter-assay precision
Ten repeated tests were conducted on three different levels of IL-2, IL-4, IL-5, IL-6, IL-10, IFN-γ and MCP-1 using different batches of reagents.
Specificity
The antibodies used in the kit have been screened for their specific reactivity with particular cytokines. After analyzing samples containing only a single recombinant cytokine protein, it was found that when using this detection method, there was no cross-reaction or background detection of cytokines in other capture magnetic bead groups.
Theoretical limit of detection
Repeat the detection of the blank sample 20 times using the same batch of reagents, and calculate the theoretical limit of detection.
Recovery
Within the detection range, the combined cytokine proteins were added to different matrices at high, medium, low concentrations.
The matrices used in these experiments were diluted 2-fold with the assay buffer before the addition of the cytokine proteins.
The results were compared with those of samples that had the same concentration of cytokines added in the assay buffer.
