General description

Product Source: Recombinant human IGF-I expressed in E. coli.

Recombinant human IGF-I (Receptor Grade) expressed in E.coli. Human insulin-like growth factor-I (IGF-I) is a single chain 70 amino acid polypeptide that shares structural homology with insulin and human IGF-II. IGF-I plays a critical role in growth, differentiation and development via autocrine, paracrine and endocrine mechanisms. It is a mitogen and also has effects on cell migration and differentiation. IGF-I is a regulator of metabolism and is also implicated in the pathophysiology of cancer, diabetes and obesity.
