Recombinant Active Protein
Insulin-like growth factor I (IGF1) is a well-characterized basic peptide believed to be secreted by the liver and to circulate in the blood. IGF1 has growth-regulating, insulin-like, and mitogenic activities. This growth factor has a major, but not absolute, dependence on Somatotropin. It is believed to be mainly active in adults in contrast to Insulin like Growth Factor 2, which is a major fetal growth factor. Recombinant Rat IGF1 produced in E. coli is a single non-glycosylated polypeptide chain containing 70 amino acids with a MW of 7,687 Da.
