| Description | Product Specifications Human IGFBP-3: Human Insulin-like Growth Factor Binding Protein-3 (rhIGFBP-3) is a 264 amino acid glycosylated protein that is one of the six 'classical' IGF binding proteins. These binding proteins have an important role in stabilizing and regulating the activity of IGFs in vivo. Human IGFBP-3 is a 40-44 kDa glycoprotein that is the most abundant IGFBP in serum and milk. It is produced by non-parenchymal hepatic cells and circulates in serum, binding IGF-I or IGF-II in conjunction with an acid labile subunit (ALS) to form a 150 kDa circulating complex at a serum concentration of about 100 nM. Free IGF-I has a half-life of ~10 min in serum. This can be increased to ~25 min if bound to IGFBP-3 and to ~15 h if complexed with IGFBP-3 and ALS.
