IGF-1 LR3
IGF-1 LR3 (Insulin-Like Growth Factor-1 Long Arg3) is a synthetic analog of naturally occurring human IGF-1, engineered to exhibit enhanced stability, increased bioavailability, and prolonged receptor activity. It differs structurally from native IGF-1 by an extended N-terminal peptide chain (13 amino acids) and a substitution of arginine for glutamic acid at position 3—modifications that dramatically reduce its affinity for IGF binding proteins (IGFBPs) while maintaining potent activity at the IGF-1 receptor (IGF-1R).
These features make IGF-1 LR3 a cornerstone compound for research into cell proliferation, differentiation, protein synthesis, recovery mechanisms, and metabolic regulation.
In pre-clinical models, IGF-1 LR3 has been utilized to investigate muscle cell regeneration, neuroprotection, glucose transport, and anabolic signaling pathways.
