More Information
Product Details
Synonyms Interleukin-2; Aldesleukin
Product Type Protein
Properties
Source/Host CHO cells
Sequence

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.

Crossreactivity Human
Biological Activity

Shows the biological function of the IL-2 moiety and exerts a prolonged circulating half-life caused by the modified Fc domain.

Purity ≥98% (SDS-PAGE)
Endotoxin Content <1EU/mg protein (LAL test; Lonza).
Reconstitution Reconstitute in 50µl sterile water.
Add 1X PBS to the desired protein concentration.
Formulation Lyophilized from 0.2μm-filtered solution in PBS.
Protein Negative Control

Fc (human) IgG1 Control (rec.) (non-lytic)

Other Product Data

Non-lytic: Acts as a long lasting fusion protein which only binds to the receptor. Mutations to the complement (C1q) and FcgR I binding sites of the IgGs Fc fragment render the fusion proteins incapable of antibody directed cytotoxicity (ADCC) and complement directed cytotoxicity (CDC).

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-γ and TNF-α and -β. 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.
