Detection Principle:

This kit uses double antibody sandwich ELISA technology. Specific anti-human IL-10 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. The IL-10 in the sample combines with the solid-phase antibody and the detection antibody. After washing sufficiently to remove free and unbound components, streptavidin HRP (sa-hrp) labeled with horseradish peroxidase was added. After washing, signal enhancer was added for incubation. After washing to remove unbound material, sa-hrp was added again. After washing again, TMB chromogenic substrate was added and incubated at room temperature in the dark to develop color. The depth of color response is positively correlated with the concentration of IL-10 in the sample. 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 10 (IL-10) is a homodimer composed of two 178 amino acid subunits. In humans, it is encoded by the IL10 gene located on chromosome 1 and consists of five exons. IL-10 is mainly secreted by monocytes, lymphocytes, type II helper T cells (Th2), mast cells, cd4+cd25+foxp3+ regulatory T cells and partially activated T cells and B cells secreted 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 - & kappa; B activity, and participate in JAK-STAT signaling pathway regulation. The immunosuppressive properties of IL-10 suggest that it may be used in clinic to inhibit rejection after organ transplantation. IL-10 also has strong anti-inflammatory properties.
