Description

Recombinant Human IGF-1 Long R3 (rhIGF-1 LR3) is a synthetic analog of native human Insulin-like Growth Factor-1 (IGF-1), engineered for enhanced biological activity and extended half-life. This analog features a substitution of arginine for glutamic acid at position 3 and a 13-amino-acid extension at the N-terminus, resulting in significantly reduced affinity for IGF-binding proteins (IGFBPs) and increased bioavailability.
