Insulin-like growth factor-I (IGF-I) is a 70 amino acid polypeptide that stimulates growth and differentiation in many cell types including rat L6 myoblasts.
IGF-I is produced in E. coli using a patented expression system and the IGF-I is correctly folded and purified by several chromatography steps to yield Receptor Grade IGF-I.
