Interleukin-2, IL-2, T-cell growth factor, TCGF.
IL2 is a secreted cytokine that is important for the proliferation of T and B lymphocytes. The receptor of this cytokine is a heterotrimeric protein complex whose gamma chain is also shared by interleukin 4 (IL4) and interleukin 7 (IL7). The expression of this gene in mature thymocytes is monoallelic, which represents an unusual regulatory mode for controlling the precise expression of a single gene. The targeted disruption of a similar gene in mice leads to ulcerative colitis-like disease, which suggests an essential role of this gene in the immune response to antigenic stimuli.
IL2 Canine Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 160 amino acids (21-155 a.a) and having a molecular mass of 18.1 kDa.
