Interleukin-22, IL-TIF, Cytokine ZCYTO18

描述:

IL-22 is a member of the IL-10 family of regulatory cytokines, which includes IL-10, IL-19, IL-20, IL-22, IL-24 and IL-26.  Members of this family share partial homology in their amino acid sequences, but they are dissimilar in their biological functions.  Produced by T lymphocytes, IL-22 inhibits IL-4 production by Th2 cells, and induces acute phase reactants in the liver and pancreas.  IL-22 signals through a receptor system consisting of IL-10R尾/CRF2-4 and IL-22R, both of which are members of the class II cytokine-receptor family.  Recombinant Human IL-22 is a 33.6 kDa, non-disulfide-linked, homodimeric protein consisting of two 147 amino acid polypeptide chains.

纯度:

Greater than 98% by SDS-PAGE gel and HPLC analyses.

生物活性:

Assay #1: Determined by its ability to activate STAT following receptor ligand interaction.
Assay #2: Measured by its ability to induce IL-10 secretion in COLO 205 (human colon carcinoma cells). The expected ED₅₀ for this effect is 0.7- 1.0 ng/ml.
