IL-22 (human):Fc (human) (rec.) (non-lytic)
|Synonyms||Interleukin-22; IL-10-related T Cell-derived-inducible Factor|
The extracellular domain of human IL-22 (aa 34-179) is fused to the N-terminus of the Fc region of a mutant human IgG1.
Shows the biological function of the IL-22 moiety and exerts a prolonged circulating half-life caused by the modified Fc domain.
|Endotoxin Content||<1EU/mg protein (LAL test; Lonza).|
Reconstitute 25µg vial in 250µl sterile water.
Reconstitute 50µg vial 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).

|Product Specification Sheet|
Interleukin-22 (IL-22), also known as IL-10 related T cell derived inducible factor (ILTIF) was initially identified as a gene induced by IL-9 in mouse T cells and mast cells. IL-22 has been shown to activate STAT1 and STAT3 in several hepatoma cell lines and upregulate the production of acute phase proteins. IL-22 is produced by normal T cells upon anti-CD3 stimulation in humans. Mouse IL-22 expression is also induced in various organs upon lipopolysaccharide injection, suggesting that IL-22 may be involved in inflammatory responses. The functional IL-22 receptor complex consists of two receptor subunits, IL-22R(CRF29) and IL-10Rβ(CRF24), belonging to the class II cytokine receptor family.
