Product Description

Insulin-like growth factor-1 (IGF-1) is a hormone similar in molecular structure to insulin. It primarily functions through binding to its specific receptor, the insulin-like growth factor 1 receptor (IGF1R). IGF-1 is one of the most potent natural activators of the AKT signaling pathway, which stimulates cell growth and proliferation, and inhibits cell apoptosis. LR3 IGF-1 (Long Arg3 IGF-1) is an 83 amino acid analog of IGF-1 comprising the complete human IGF-1 sequence with the substitution of an Arg for the Glu at position 3 (hence R3), and a 13 amino acid extension peptide at the N-terminus. The LR3 IGF-1 has much higher stability and biological activity.
