pro IGF-II (pro Insulin-like Growth Factor-2)

Product Description:

  • Endotoxin-free
  • Animal-derived product free
  • Lyophilized and Carrier Free (CF)
  • Available in Bulk
  • High Stability

Xeno-free pro-IGF-IIHuXp is expressed in human 293 cells as a monomeric glycoprotein with an apparent molecular mass of 25 kDa. Glycosylation contributes to stability in cell growth media and other applications. IGF-II expressed in E. coli is typically 7.5 kDa and nonglycosylated. This cytokine is produced in a human cell expression system with serum-free, chemically defined media.

Technical Specifications:

  • Species: Human
  • Expression: HEK293 Cell Expressed
  • Activity: Typically ≤50 ng/mL EC50
  • Purity: >95%
  • Endotoxin: <1 EU/μg
  • Molecular Mass: 25 kDa, monomer, glycosylated
  • Formulation: 10 mM Tris-HCl pH 7.4 + 350 mM NaCl

Purity Confirmation:

The protein was resolved by SDS-polyacrylamide gel electrophoresis and the gel was stained with Coomassie blue.

Activity Assay:

The activity was determined by the dose-dependent stimulation of the proliferation of MCF-7 cells (human breast cancer cell line).

Reconstitution Buffer:

Briefly centrifuge the vial before opening. It is recommended to reconstitute the protein in sterile 1xPBS containing 0.1% endotoxin-free recombinant human serum albumin (HSA).

Synonyms: proIGFII, pro IGF II
