Human IL-21, research grade

05MT00034

Recombinant human IL-21 (interleukin 21) can promote differentiation of TH17 or T follicular helper (Tfh) cells, expansion of CD8+ T cells, as well as B and NK cell development. Thus, the pleiotropic cytokine regulates several aspects of lymphoid cell function and has central roles for humoral immunity. IL-21 has been associated with allergies, cancer, and viral infections. Recombinant protein human IL-21 was developed for use in various applications, such as cell culture, differentiation studies, and functional assays.
