Specification

• Species: Human
• Source: E.coli
• Tag: His
• Protein Length: Ala25-Glu91
• Description: Insulin like Growth Factors 2 (IGF-II) is a 7.48 kDa member of the Insulin-like Growth Factors with 67 amino acid residues. IGF-II is mainly expressed from placenta, extravillous trophoblasts, leydig cells, syncytiotrophoblasts, cytotrophoblasts, peritubular cells. IGF-II regulating fetoplacental development and tissue differentiation. In adults, IGF-II signaling involves glucose metabolism in adipose tissue, skeletal muscle and liver. It also has important implications for metabolic disorders and cancer.
• Form: Lyophilized
• Bio-activity: Measure by its ability to induce MCF-7 cells proliferation. The ED50 for this effect is < 3 ng/mL. The specific activity of recombinant human IGF-II is > 3 × 10⁵ IU/mg.
• Molecular Mass: The protein has a calculated MW of 8.28 kDa.
  The protein migrates as 11 kDa under reducing condition (SDS-PAGE analysis).
• Endotoxin: < 0.1 EU/μg of the protein by the LAL method.
• Purity: >98% as determined by SDS-PAGE analysis.
• Storage: This product is stable after storage at:
  -20 centigrade for 12 months in lyophilized state from date of receipt.
  -20 or -80 centigrade for 2 weeks under sterile conditions after reconstitution.
  Avoid repeated freeze/thaw cycles.
• Storage Buffer: Lyophilized from a 0.2 μm filtered solution of PBS, pH 8.0.
• Reconstitution: It is recommended to reconstitute the lyophilized protein in sterile H2O to a concentration not less than 200 μg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.
• Shipping: The product is shipped with polar packs. Upon receipt, store it immediately at -20 centigrade or lower for long term storage.
