Human IGFI Protein (IGF-HE001) Summary

Product Description	Recombinant Human IGFI Protein is expressed from E.coli without tag.It contains Gly49-Ala118.
Product Background	The insulin family consists of insulin, insulin-like growth factor 1 (IGF-1), insulin-like growth factor 2 (IGF-2), their receptors (IR, IGF-1R and IGF-2R), and their binding proteins.Insulin-like growth factor I (IGF-I) is a polypeptide hormone produced mainly by the liver in response to the endocrine GH stimulus, but it is also secreted by multiple tissues for autocrine/paracrine purposes.
Product Category	Recombinant Protein / Antibody discovery / Antibody discovery \| Others
