A novel cytokine, designated IL-TIF for IL-10 related T cell-derived inducible factor and IL-22, was recently identified (1–3). The receptor for IL-22 (IL-22R, also termed CRF2–9 and IL-TIF-R1 chain) is a new member of the class II cytokine receptor family (3,4). IL-22R forms a complex with IL-10 receptor b chain and mediates IL-22 signaling. IL-22 and its receptor activate JAK-STAT signaling pathway. IL22R is expressed in normal liver and kidney and their cell lines HepG2 and TK-10. A soluble form of IL-22 receptor, also termed IL-22 binding protein (IL-22BP) and IL-22 receptor-a 2 (IL-22RA2), was identified very recently (5–7). IL-22BP prevents binding of IL-22 to the functional cell surface IL-22R complex and neutralizes IL-22 activity. LPS induces IL-22 expression, which indicates the role of IL-22 in inflammatory response.
Synthetic peptide (QSSNFENILTWDSGPE) corresponding to amino acids 31 to 46 of human IL-22R precursor (1).
Storage and Stability:Lyophilized powder may be stored at 4°C for short-term only. Reconstitute to nominal volume by adding sterile 40-50% glycerol and store at -20°C. Reconstituted product is stable for 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
