背景介绍 IL-2 is produced mainly by T- cells expressing the surface antigen CD4 following cell activation by mitogens or allogen. Interleukin-2 (IL-2) has multiple, sometimes opposing, functions during an inflammatory response. It is a potent inducer of T-cell proliferation and T- helper 1 (Th1) and Th2 effector T-cell differentiation and provides T cells with a long-lasting competitive advantage resulting in the optimal survival and function of memory cells. In a regulatory role, IL-2 is important for the development, survival, and function of regulatory T cells, it enhances Fas-mediated activation-induced cell death, and it inhibits the development of inflammatory Th17 cells. Thus, in its dual and contrasting functions, IL-2 contributes to both the induction and the termination of inflammatory immune responses. 产品介绍 Recombinant Interleukin-2 is a disulfide-linked monomer protein consisting of 133 amino acid residues, migrates as an approximately 15 kDa protein under non-reducing and reducing conditions in SDS-PAGE. Optimized DNA sequence encoding human Interleukin-2 mature chain was expressed in E. coli.
