MW: 31,674 Da. Purity >95%, as determined by SDS-PAGE and HPLC. IGFBPs are synthesized in the liver and are produced also by various tumor cell lines and cell types. IGFBPs are high affinity binding proteins for IGF. The major fraction of both types of IGF circulating in the blood are bound non- covalently to these carrier proteins. IGF binding proteins modulate IGF activities by increasing their plasma half lives and by inhibiting or promoting the interactions of IGF with receptors on certain t
