IGF-1 LR3 (Long R3 Insulin-like Growth Factor-1) is a synthetic, long-acting analog of native IGF-1 used as a reference compound in laboratory growth-factor and IGF-receptor research. It differs from native IGF-1 by an arginine substitution at position 3 (Arg3) and a 13-amino-acid N-terminal extension, modifications that sharply reduce its binding to IGF-binding proteins (IGFBPs) and […]
