Recombinant Human IL-22 Protein Summary

Description
A non-disulfide-linked homodimeric protein containing two 147 amino acid polypeptide chains corresponding to IL-22 Source: E. coli

Uniprot ID: Q9GZX6

Amino Acid Sequence: MAPISSHCRL DKSNFQQPYI TNRTFMLAKE ASLADNNTDV RLIGEKLFHG VSMSERCYLM KQVLNFTLEE VLFPQSDRFQ PYMQEVVPFL ARLSNRLSTC HIEGDDLHIQ RNVQKLKDTV KKLGESGEIK AIGELDLLFM SLRNACI

This lyophilized preparation is stable for 12 months from date of receipt at -20 to -70 degrees C, preferably desiccated. Upon reconstitution, the preparation can be stored for 1 month at 2-8 degrees C under sterile conditions, and for 3 months at -20 degrees C to -70 degrees C. Use a manual defrost freezer and avoid repeated freeze-thaw cycles. Stock solutions should be aliquoted and stored at < -20 degrees C. Further dilutions should be made in appropriate buffered solutions

Details of Functionality
IL22 Protein is fully biologically active when compared to standard. The ED50 as determined by inducing IL-10 secretion of human COLO 205 cells is less than 0.3 ng/ml, corresponding to a specific activity of > 3.3 x 10^6 IU/mg.

Background

IL-22 is belonging to 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 and dendritic cells, IL-10 contributes to the inflammatory response in vivo. IL-22 signals through CRF2-4 and IL-22. It along with IL-17 is rapidly produced by splenic LTi-like cells and can be also produced by Th17 cells and likely plays a role in the coordinated response of both adaptive and innate immune systems.
