Chicken Insulin-like Growth Factor-II
The Eagle Bioscience’s Chicken Insulin-like Growth Factor-II (IGF-II) is for research use only and not to be used for diagnostic procedures.
IGF-II is produced in E.coli using a patented expression system.
Chicken IGF-II is a single chain 66 amino acid polypeptide that shares structural homology with human IGF-II. Twelve amino acids are different compared to the sequence of human IGF-II. Chicken IGF-II has been shown to stimulate growth and differentiation in many cell types including chick embryo fibroblasts. Receptor Grade chicken IGF-II is a high quality research reagent particularly for use in studies on cellular and animal growth, for use in specific assays for chicken IGF-II and other general research purposes.
