Human IL-21(Interleukin-21) Introduction
IL21 is a cytokine with immunomodulatory activity. May promote the transition between innate immunity and adaptive immunity. Induces the production of IgG(1) and IgG(3) in B cells. It may act synergistically with IL15 in the proliferation and maturation of natural killer (NK) cells. It can regulate the proliferation of mature B cells and T cells in response to activation stimuli. Co-stimulates the production of interferon gamma in T cells and NK cells with IL15 and IL18. During the T cell-mediated immune response, the activation and maturation of dendritic cells (DC) may be inhibited.

Human IL-21(Interleukin-21) ELISA KIT Test Method
This kit uses sandwich ELISA to detect the concentration of human IL-21 .
Human IL-21-specific monoclonal antibody has been pre-coated in the wells of the supplemented microplate. Standards samples and controls are added to interact with the immobilized antibody. A sandwich complex is formed by additional anti-Rabbit IL-21 antibody with HRP-Streptavidin. TMB solution is added to react with the sandwich forming optical signal measured by microplate reader. The concentration of rabbit IL-21 in the sample can be calculated by comparing the absorbance of the sample with the standard curve.
