Source HEK293-derived Human IGF-I protein Gly49-Ala118 (Accession# P05019-1) with a human IgG1 Fc tag at the N-terminus.
Predicted Molecular Mass 33.7 kDa
SDS-PAGE 34-36 kDa, reducing (R) conditions
Formulation Lyophilized from sterile PBS, pH 7.4. Normally 5% trehalose and 5% mannitol are added as protectants before lyophilization.
Reconstitution Briefly centrifuge the tube before opening. Reconstitute at 0.1-0.5 mg/mL in sterile water.
Storage
It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
  • Until expiry date, -20℃ to -80℃ as lyophilized proteins.
  • 3 months, -20℃ to -80℃ under sterile conditions after reconstitution.
Shipping The product is shipped at ambient temperature. Upon receipt, store it immediately at the recommended temperature.

Background

Insulin-like-growth factor 1 (IGF1), a 70 amino-acid peptide hormone is the principal mediator of biochemical effects of growth hormone (GH). IGF1 is an important growth factor in the regulation of cell proliferation and differentiation. IGF1 is largely synthesized in the liver (75%) and, to a lesser extent, in peripheral tissues. IGF1 have been shown to play an essential role in preventing the formation of fatty liver. IGF1 is a potent mitogen and is inhibited by IGF-binding protein-3 (IGFBP3). High serum IGF1 and low IGFBP3 are associated with increased risk of several carcinomas.
