Chicken IGF-II, recombinant protein (Receptor Grade)
Insulin-like Growth Factor-II, Chicken, Receptor Grade, recombinant Synonyms: insulin like growth factor-2, IGF-2, Somatomedin A, ILGF2, T3M-11-derived growth factor,
Product Specifications Chicken IGF-II:
The Product: Chicken IGF-II is a polypeptide comprising of 66 amino acids, twelve of which differ from the amino acid sequence of human IGF-II. Chicken IGF-II has been shown to stimulate growth and differentiation in most cell types, including L6 myoblasts and chicken embryo fibroblasts.
Source: Chicken IGF-II is produced in E. coli and several purification steps are employed to yield Receptor Grade chicken IGF-II.
