Biotin anti-human IL-22

Each lot of this antibody is quality control tested by ELISA assay. For use as an ELISA detection antibody, a concentration range of 0.5-2 µg/ml is recommended. It is recommended that the reagent be titrated for optimal performance. To obtain a linear standard curve, serial dilutions of IL-22 recombinant protein ranging from 8000 to 125 pg/ml are recommended.

ELISA Detection - Quality tested

ELISA Detection: The biotinylated Poly5161 antibody is useful as a detection antibody in a sandwich ELISA assay, when used in conjunction with purified poly5161 (Cat. No. 516101) antibody as the capture antibody and recombinant human IL-22 (Cat. No. 571309) as the standard.

IL-22 is a cytokine structurally related to IL-10. Originally identified as a murine gene induced by IL-9 in T and mast cells, IL-22 was initially designated ILTIF (IL-10-related T cell-derived inducible factor). IL-22 belongs to a family of cytokines with limited homology to IL-10, namely IL-10, IL-19, IL-20, IL-24, IL-26, and the IFN-λs, IL-28A, IL-28B and IL-29. Human IL-22 shares 79% amino acid identity with murine IL-22 and 25% identity with human IL-10. IL-22 biological activity is initiated by binding to a cell surface complex composed of IL-22R1 and IL-10R2 receptor chains. Activity is further regulated through interactions with the soluble binding protein, IL-22BP, which shares sequence similarity with an extracellular region of IL-22R1 (sIL-22R1). Both chains of the IL-22R complex belong to the class II CRF. Two types of IL-22 binding receptors have been discovered, a membrane-bound receptor and a soluble receptor, both encoded by different genes. IL-22 is produced by Th17 cells and newly identified Th22 cells. It plays a critical role in mucosal immunity in addition to the deregulated inflammation observed in autoimmune diseases.
