Recombinant Mouse IL22 Protein, PEG Online Inquiry

  • Cat#:
  • RP-1824M
  • Product Name:
  • Recombinant Mouse IL22 Protein, PEG
  • Synonym:
  • IL-TIF, TIFa, IL-10-related T-cell-derived-inducible factor, IL-22, ILTIF, IL-D110, zcyto18, MGC79382, MGC79384, TIFIL-23.
  • Description:
  • 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:
  • E.coli
  • Purity:
  • Greater than 98.0% as determined by: (a) Analysis by Gel-Filtration. (b) Analysis by SDS-PAGE.
  • Bioactivity:
  • The ED50 as determined by STAT3 phosphorylation assay in HepG cells. The activity in vitro was found to be ~ 10% compared to the non-pegylated mouse IL22.
  • Formulation:
  • Lyophilized from a concentrated solution at 0.65mg/ml containing 0.003mM NaHCO3.
  • Stability:
  • Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃
  • Reconstitution:
  • It is recommended to reconstitute the lyophilized pegylated mouse Interleukin -22 in sterile 0.4% NaHCO3 adjusted to pH 8-9 not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
  • Storage:
  • Lyophilized pegylated murine IL22 although stable at room temperature for several days, should be stored desiccated below -20?C. Upon reconstitution at 0.1mg/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.
