Description

IGF-1 LR3 is a synthetic 83-amino acid analog of human insulin-like growth factor-1 (IGF-1) that has been structurally modified to enhance its biological activity. The 'LR3' designation refers to two key modifications: an arginine substitution at position 3 (replacing glutamic acid) and a 13-amino acid N-terminal extension peptide. These modifications dramatically reduce binding to IGF binding proteins (IGFBPs), resulting in a significantly longer half-life and greater bioavailability compared to native IGF-1. In research settings, IGF-1 LR3 demonstrates approximately 2-3 times greater potency than native IGF-1 in stimulating cellular proliferation, making it a valuable tool for studying growth factor biology, muscle development, and metabolic regulation.
