Active Recombinant Human IGF1 Protein (Gly49-Ala118, Glu51Arg), GMP Grade, Animal-Free

• Cat.No.: IGF1-19HG
• Product Overview: GMP recombinant human LR3 IGF-I/IGF-1 protein (Gly49-Ala118, Glu51Arg) without tag was expreessed in E. coli, produced using non-animal reagents in an Animal-Free laboratory and manufactured and tested under cGMP guidelines.

Specification

• Species: Human
• Source: E.coli
• Protein Length: Gly49-Ala118, Glu51Arg
• Description: The protein encoded by this gene is similar to insulin in function and structure and is a member of a family of proteins involved in mediating growth and development. The encoded protein is processed from a precursor, bound by a specific receptor, and secreted. Defects in this gene are a cause of insulin-like growth factor I deficiency. Alternative splicing results in multiple transcript variants encoding different isoforms that may undergo similar processing to generate mature protein.
• Bio-activity: Measured in a serum-free cell proliferation assay using MCF-7 human breast cancer cells. The ED50 for this effect is 0.3-1.5 ng/mL. IGFBP-3 does not inhibit its activity.
• Molecular Mass: Predicted Molecular Mass: 9 kDa
  SDS-PAGE: 8 kDa, reducing conditions
• N-terminal Sequence Analysis: Met-Phe-Pro-Ala-Met-Pro-Leu-Ser-Ser-Leu
• Endotoxin: <0.01 EU/ μg of the protein by the LAL method.
• Purity: >95%, by SDS-PAGE visualized with Silver Staining and quantitative densitometry by Coomassie® Blue Staining.
• Storage: Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
  A minimum of 12 months when stored at ≤ -20 centigrade as supplied. Refer to lot specific COA for the Use by Date.
  1 month, 2 to 8 centigrade under sterile conditions after reconstitution.
  3 months, ≤ -20 centigrade under sterile conditions after reconstitution.
• Storage Buffer: Lyophilized from a 0.2 μm filtered solution in Acetic Acid.
• Reconstitution: Reconstitute at 100-200 μg/mL in sterile 100 mM Acetic Acid
• Shipping: The product is shipped with polar packs.
