IGF-1 LR3 (Long-Arg3 Insulin-like Growth Factor 1) is a recombinant 83-amino-acid analog of human IGF-1, modified with an N-terminal 13-amino-acid extension and an Arg-3 substitution that significantly reduces binding to IGF binding proteins. Extensively studied in preclinical research and cell culture applications for its role in IGF-1 receptor signaling, cellular proliferation, and growth pathway research. Lyophilized powder, ≥98% purity, third-party tested. For laboratory and research use only — not for human consumption.
