IGFBP3 Antibody

The Insulin-like growth factor-binding proteins, or IGFBPs, are a family of homologous proteins that have co-evolved with the IGFs. They serve not only as shuttle molecules for the soluble IGFs, but also confer a level of regulation to the IGF signaling system. IGFBP3 is the most abundant IGFBP and is complexed with roughly 80% of the serum IGFs.
