IGF-1 LR3

IGF-1 LR3 is not the native hormone; it is a synthetically engineered, 83-amino acid analog of Insulin-like Growth Factor-1 (IGF-1) with two critical modifications: an N-terminal 13-amino acid extension and an Arg³→Leu substitution. This design dramatically reduces its binding to inhibitory IGF Binding Proteins (IGFBPs), resulting in a molecule with significantly prolonged half-life and vastly enhanced in-vitro and in-vivo bioactivity. For researchers in muscle physiology, metabolism, and tissue engineering, it represents the definitive tool to study potent, sustained anabolic signaling. 🧬 Imagine Unleashing Uninhibited Growth Factor Action. Native IGF-1's activity is tightly controlled by binding proteins. IGF-1 LR3's "engineered escape" from this regulation allows you to investigate the full, unattenuated potential of the IGF-1 receptor pathway.
