Description
IGF-1 LR3 (Long R3 IGF-1) is a recombinant 83-amino-acid analogue of human insulin-like growth factor 1, with arginine in place of glutamic acid at position 3 and a 13-residue N-terminal extension that reduces binding to IGF-binding proteins. It is studied in cell-culture research on IGF-1 receptor signalling. Supplied lyophilised, for in vitro research only.
