Description
Long R3 insulin-like growth factor-1. An 83-residue analogue of human IGF-1 with an arginine substitution at position 3 and a 13-residue N-terminal extension. Supplied as a lyophilized powder, sealed under nitrogen, in a 3 mL clear borosilicate vial with a flip-off cap. Each production lot is assayed by an independent laboratory for purity by RP-HPLC and identity by ESI-MS; the lot number printed on the label resolves to that certificate.
