Chimerigen
IL-2 (human):Fc (human) (rec.) (non-lytic)
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 | |
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). |
Declaration | Manufactured by Chimerigen. |
Shipping and Handling | |
Shipping | BLUE ICE |
Short Term Storage | +4°C |
Long Term Storage | -20°C |
Handling Advice |
Avoid freeze/thaw cycles. Centrifuge lyophilized vial before opening and reconstitution. |
Use/Stability |
Stable for at least 1 year after receipt when stored at -20°C. Working aliquots are stable for up to 3 months when stored at -20°C. |

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.
