IGF-1 LR3 1mg/Vial – Long-Acting Insulin-Like Growth Factor Analog​
Brand: ACDC | CAS No.: 946870-92-4 | Purity: 99.7% min.​
IGF-1 LR3 (Long R3 Insulin-Like Growth Factor-1) is a synthetic modified peptide engineered for enhanced stability and sustained biological activity. This pharmaceutical-grade research tool features a 13-amino-acid N-terminal extension and arginine substitution at position 3—key modifications that drastically reduce binding to IGF-binding proteins (IGFBPs), ensuring consistent availability in experimental models. Supplied as a sterile filtered white lyophilized powder, it’s widely used in muscle growth research, metabolic pathway studies, and tissue repair investigations.​
