The Eagle Bioscience’s Chicken IGF-I is for research use only and not to be used for diagnostic procedures.
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.
Chicken insulin-like growth factor-I is a single chain 70 amino acid polypeptide that shares structural homology with human IGF-I and chicken IGF-II. Eight amino acids are different compared to the sequence of human IGF-I. Chicken insulin-like growth factor-I has been shown to stimulate growth and differentiation in many cell types including chick embryo fibroblasts. Receptor Grade chicken insulin-like growth factor-I is a high-quality research reagent particularly for use in studies on cellular and animal growth, for use in specific assays for chicken IGF-I and other general research purposes.
