Active Recombinant Human IL2, Fc-tagged

• Cat.No.: IL2-306H
• Product Overview: The extracellular domain of human IL-2 (aa 21-153) is fused to the N-terminus of the Fc region of a mutant human IgG1.

Specification

• Description: Interleukin-2 (IL-2) is a 133 amino acid glycoprotein with one intramolecular disulfide bond and variable glycosylation. It is secreted by activated T cells and induces proliferation and maturation of activated T cells, natural killer cells, and lymphokine activated killer cells. IL-2 also stimulates proliferation of antibody-producing B cells, activates neutrophils, and induces mononuclear cells to secrete IFN-gamma; and TNF-alpha; and -beta. Moreover, studies have shown that IL-2 is required for activation-induced apoptosis, an important hemeostatic mechanism in the immune system, which is involved in the maintenance of peripheral tolerance to self-antigens.
