Product Specifications
Source:
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.
Description:
Tuna insulin-like growth factor-I (IGF-I) is a single chain 68 amino acid polypeptide that shares structural homology with human IGF-I. Seventeen amino acids are different compared to the sequence of human IGF-I. Three of these changes occur in the B-domain, seven in the variable C-domain, two in the A-domain and five in the D-domain. Tuna IGF-I can be used for a variety of in vivo and in vitro applications including those investigating the actions of growth hormone.
