Detection Principle:

This kit uses double antibody sandwich ELISA technology. Specific anti-human il-17a  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-17A in the sample; 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 is positively correlated with the concentration of IL-17A 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 17a (IL-17 or IL-17A), a representative member of the IL-17 family of cytokines, is produced by helper T lymphocytes and can be induced by IL-23. IL-17 cytokines can effectively recruit monocytes and neutrophils to the site of inflammation by increasing the production of chemokines in tissues, thereby delaying the onset of inflammation. When extracellular pathogens invade the immune system, IL-17, as a proinflammatory cytokine, will respond and destroy pathogen cells. IL-17 can play a synergistic role with tumor necrosis factor and IL-1. IL-17 family is associated with many immune / autoimmune related diseases, such as rheumatoid arthritis, asthma, lupus, allograft rejection, anti-tumor immunity, psoriasis, multiple sclerosis.
