Bream IGF-I, recombinant protein (Receptor Grade)
Bream (Pagrus auratus) Insulin-like Growth Factor-I (Receptor Grade) Synonyms: Igf-1, insulin-like growth factor-1, Somatomedin c, ILGF1, Mechano growth factor
Product Specifications Bream IGF-I:
Recombinant red sea bream (Pagrus auratus) insulin-like growth factor-I s a 67 amino acid polypeptide. IGF-I stimulates growth and differentiation in many cell types and mediates many of the anabolic properties of growth hormone. Recombinant red sea bream (Pagrus auratus) IGF-I is identical to [Gly1] gilthead sea bream (Sparus aurata) IGF-I and [Gly1] black bream (Acanthopagrus butcheri) IGF-I, as glycine replaces the serine at position 1 in these proteins.
Source: Red sea bream IGF-I is synthesized in E. coli using a patented expression system and the bream IGF-I is correctly folded and then purified by several liquid chromatography purification steps to yield receptor grade bream IGF-I.
