Mouse Il22 (Q9JJY9, 146 amino acids) partial recombinant protein expressed in Escherichia coli.
Theoretical MW (kDa):
Escherichia coli expression system
>= 97% by SDS-PAGE and HPLC
< 0.1 ng/ug
Recombinant murine IL-22 is fully biologically active when compared to a standard. The ED50 as determined by its ability to induce IL-10 secretion in Colo205 cells is less than 0.5 ng/mL, corresponding to a specific activity of 2 x 106 IU/mg.
Lyophilized from 1X PBS
Store at -20°C on dry atmosphere. After reconstitution with sterilized water, store at -20°C. Aliquot to avoid repeated freezing and thawing.
