Description
Mono-pegylated (with 20 kDa PEG) recombinant mouse interleukin 22 is one polypeptide chain containing 147 amino, an additional Ala at N-terminus and one molecule of PEG 20 kDa at its N-terminus, having an expected molecular mass of ~ 36 kDa as determined by MS. However due to enlarged hydrodymanic volume it runs on the SDS-PAGE as 50 kDa protein and in gel-filtration on Superdex 200 as over 200 kDa protein. For more details see L. Niv-Spector et al. Protein Eng Des Sel. (PEDS) 25:397-404 (2012) .

Assay Protocol
It is recommended to reconstitute the lyophilized pegylated mouse IL22 in sterile water or sterile 0.4% NaHCO3 adjusted to pH 8-9, not less than 100µg/ml, which can then be further diluted with other aqueous solutions.
Endotoxin
< 0.1 ng/µg of protein (< 1EU/µg)
Purity
> 98.0% as determined by Gel filtration and SDS-PAGE gel.
Bioactivity
Recombinant murine IL-22 is biologically active when compared to standard using STAT3 phosphorylation assay in HepG cells. Its acrtivity in vitro is ~ 10% compared to the non-pegylated mIL22.
