Insulin-like Growth Factors (IGF´s), Biotinylated IGF´s and Analogs, Biotinylated Insulin

Chicken IGF-I, recombinant protein (Receptor Grade)

Insulin-like Growth Factor-I, Chicken, recombinant Synonyms: Igf-1, insulin-like growth factor-1, Somatomedin c, ILGF1, Mechano growth factor

Product Specifications Chicken IGF-I:

The Product: Chicken IGF-I is a polypeptide comprising 70 amino acids, eight of which differ from the amino acid sequence of human IGF-I. Chicken IGF-I has been shown to stimulate growth in many cell types, including rat L6 myoblasts and chicken embryo fibroblasts, hepatocytes,adipocytes and myoblasts.

Link to Sequence:
Source: Chicken IGF-I is produced recombinantly in E. coli using a patented expression system. The chicken IGF-I molecule is correctly folded and several chromatography purification steps are employed to yield Receptor Grade chicken IGF-I.
