Research Overview
IGF-1 LR3 (Long R3 IGF-1) is a modified form of insulin-like growth factor-1 with an arginine substitution at position 3 and a 13-amino acid N-terminal extension.
Mechanism of Action
Binds IGF-1 receptors with reduced affinity for IGF binding proteins (IGFBPs), resulting in enhanced bioavailability and prolonged receptor activation.
Research Applications
Cell proliferation studies, muscle cell differentiation, satellite cell activation, metabolic pathway research, cancer biology investigation.
Key Research Findings
3x longer half-life than native IGF-1. Reduced IGFBP binding increases free circulating levels in preclinical models.
