Anti-Mouse IGF-BP5 Antibody

IGFBP5 is expressed by fibroblasts, myoblasts and osteoblasts, making it the predominant IGFBP found in bone extracts. IGFBP5 has a strong affinity for hydroxyapatite, allowing it to bind to bone cells. When bound to extracelluar matrix, IGFBP5 is protected from proteolysis and potentiates IGF activity, but when it is soluble, IGFBP5 is cleaved to a biologically inactive 21 kDa fragment. Mouse, human and rat IGFBP5 share 97% identity.
