Product Specifications


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.


Bream insulin-like growth factor-I (IGF-I) is a single chain 67 amino acid polypeptide that shares structural homology with human IGF-I. It is identical to [Gly1] gilthead sea bream (Sparus aurata) IGF-I and [Gly1] black bream (Acanthopagrus butcheri) IGF-I as glycine replaces the serine in these IGFs. Bream IGF-I can be used for a variety of in vivo and in vitro applications including those investigating the actions of growth hormones.
