IL 22 Mouse, PEG

Pegylated Interleukin-22 Mouse Recombinant produced in E.Coli is a single, non-glycosylated homodimeric polypeptide chain containing 147 amino acids and an aditional Ala amino acid at N-terminus having a molecular mass of 36 kDa as determioned by mass spectometry. However due to enlarged hydrodymanic volume it runs on the SDS-PAGE as a 50 kDa protein and in gel-filtration on Superdex 200 as over 200 kDa protein. The Murine IL-22 is Mono-pegylated (with 20 kDa PEG) purified by proprietary chromatographic techniques.

Source

Escherichia Coli.

Buffer

Lyophilized from a concentrated solution at 0.65mg/mL containing 03mM NaHCO3.

Storage Conditions

Lyophilized pegylated murine IL22 although stable at room temperature for several days, should be stored desiccated below -20C. Upon reconstitution at 0.1 mg/mL pegylated mouse IL22 and up to 2mg/mL, filter and sterilized, the protein can be stored at 4 degrees Celsius for several weeks making it suitable for long term infusion studies using osmotic pumps. At lower concentration addition of a carrier protein (0.1% HSA or BSA) is suggested. Please prevent freeze-thaw cycles.
