Anti-Human IGFBP-3 Purified No Carrier Protein (Clone: 84728)

Insulin-like growth factor binding protein 3, also known as IGFBP3, is a member of the insulin-like growth factor binding protein (IGFBP) family that are cysteine-rich proteins that act as a carrier protein. The protein forms a ternary complex with insulin-like growth factor acid-labile subunit (IGFALS) and either insulin-like growth factor (IGF) I or II. In this form, it circulates in the plasma, prolonging the half-life of IGFs and altering their interaction with cell surface receptors.
