Cat no: I7661-16C

Insulin-Like Growth Factor Binding Protein 4, Recombinant, Human (IGFBP4, BP-4, HT29-IGFBP, IBP4)

The superfamily of insulin-like growth factor (IGF) binding proteins include the six high-affinity IGF binding proteins (IGFBP) and several low-affinity binding proteins referred to as IGFBP related proteins (IGFBP-rP). All IGFBP superfamily members are cysteine-rich proteins with conserved cysteine residues, which are clustered in the amino- and carboxy-terminal thirds of the molecule. IGFBPs modulate the biological activities of IGF proteins. Some IGFBPs may also have intrinsic bioactivity that is independent of their ability to bind IGF proteins. Post-translational modifications of IGFBP, including glycosylation, phosphorylation and proteolysis, have been shown to modify the affinities of the binding proteins to IGF.\n\nSource:\nyeast\n\nBiological Activity:\nBinding activity of human IGF-BP 4 is determined by the inhibition activity of both IGF I and II.\n\nStorage and Stability:\nLyophilized powder may be stored at -20 degrees C. Reconstitute to with sterile dH2O or buffer, aliquot and store at -20 degrees C. Reconstituted product is stable for 6 months at -20 degrees 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.
