Rat IL-21(Interleukin-21) Introduciton
Interleukin 21 (IL-21) is a protein that in humans is encoded by the IL21 gene. Interleukin-21 is a cytokine that has potent regulatory effects on cells of the immune system, including natural killer (NK) cells and cytotoxic T cells that can destroy virally infected or cancerous cells. This cytokine induces cell division/ proliferation in its target cells.

Rat IL-21(Interleukin-21) ELISA Kit Test method
This kit uses sandwich ELISA to detect the concentration of Rat IL-21.
Rat IL-21-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-Mouse 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 Bovine IL-21 in the sample can be calculated by comparing the absorbance of the sample with the standard curve.
