The insulin-like growth factor IGF-1 is a growth-promoting peptide that is structurally related to insulin. The majority of IGF peptides are not found in a free form, but rather in complex with IGF-binding proteins (IGFBP) protecting the growth factor from proteolysis. IGF-1 exhibits a variety of cellular functions, especially by activating IGF-receptor including regulation of hormone synthesis and secretion, chemoattractant migration, immune cell recognition, and neuromodulation.

Synonyms: Somatomedin C, IGF-I, IGFI, IGF1, IGF-IA, Mechano growth factor, MGF

Protein informations: Insulin-Like Growth Factor-I, human recombinant produced in E.Coli, is a single, non-glycosylated, polypeptide chain containing 70 amino acids and having a molecular mass of 7655 Dalton. IGF-I is purified by proprietary chromatographic techniques.

Purity: > 98% by SDS PAGE

Biological activity:The ED50, calculated by the dose-dependent proliferation of murine BALBC 3T3 cells (measured by 3H-thymidine uptake) is < 1.0 ng/ml, corresponding to a specific activity of 1.000.000 U/mg. For most in-vitro applications, IGF-I exerts its biological activity in the concentration range of 0.2-20 ng/ml.
