Human IL-4(Interleukin 4) Introduciton
IL4 is involved in at least several B cell activation processes and other cell types. It is a costimulator of DNA synthesis. It induces the expression of MHC class II molecules on resting B cells. It enhances the secretion and cell surface expression of IgE and IgG1. It also regulates the low-affinity Fc receptor expression of IgE (CD23) on lymphocytes and monocytes. Genetic variation of IL4 may be a cause of susceptibility to ischemic stroke (ISCHSTR); also known as cerebrovascular accident or cerebral infarction.
Human IL-4(Interleukin 4) ELISA Kit Test method
This kit uses sandwich ELISA to detect the concentration of human IL-4.
Human IL-4-specific monoclonal antibody has been pre-coated in the wells of the supplied microplate.Standards samples and controls are added to interact with the immobilized antibody. A sandwich complex is formed by additional anti-human IL-4 antibody with HRP-Streptavidin.TMB solution is added to react with the sandwich forming optical signal measured by microplate reader.The concentration of human IL-4 in the sample can be calculated by comparing the absorbance of the sample with the standard curve.
