Human IL-2 Recombinant Active Protein

Interleukin-2 (IL-2 or T-cell growth factor) is an immunomodulatory cytokine produced by stimulated T-cells. IL-2 activity is signaled via interaction with the IL-2R receptor. Recombinant IL-2 produced in E. coli is a single non-glycosylated polypeptide chain containing 134 amino acids with a MW of 15,517 Da. Recombinant human IL-2 has a Ser residue instead of Cys at position 126.
