||Recombinant Rat Insulin-like Growth Factor Binding Protein-4 (rIGFBP-4) produced inE.coliis a 233 amino acid glycosylated protein.MW =25.7 kDa.
||IGFBP-4 is one of the six "classical" IGF binding proteins that play an important role in stabilizing and regulating the activity of IGFs in vivo. Rat IGFBP-4 binds both IGF-I and IGF-II and modifies their biological activity and bioavailability.
||> 95% rat IGFBP-4 (by Mass Spectrometry).
||Binding of IGF-I: IC50 0.24 nM.
|State And Appearance:
||Lyophilized white powder dried from 10mM HCl and stored under dry nitrogen at a slight vacuum (-25 kPa).
||At least 2 years at 2 - 4°C (lyophilized).
