Human IGF-BP5 is a 28.6kD cysteine-rich secreted protein produced by vascular smooth muscle cells. It is the major IGF-binding protein present in bone tissue and helps potentiate the action of IGF-I on smooth muscle cells, fibroblasts or osteoblasts. Studies show that IGF-BP5 acts as a growth inhibitor and pro-apoptotic agent in breast cancer cells. IGF-BP5 overexpressing mice show an increase in neonatal mortality, reduced female fertility, whole body growth inhibition, and retarded muscle development. Recombinant human IGF-BP5 is a 28.6kD protein consisting of 253 amino acid residues. Source: E.coli Endotoxin: 0.1ng/ug Biological Activity: The ED50 as determined by its ability to inhibit IGF-II induced proliferation of MCF-7 is 0.3ug/ml, in the presence of 15ng/ml of human IGF-II. Storage and Stability: Lyophilized powder may be stored at 4°C for short-term only. Stable for at least 6 months at -20°C. Reconstitute with sterile ddH2O, aliquot and store at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer. Molecular Weight: 28.6kD |
