Description
Research Overview
IGF-1 LR3 (Long Arginine 3 Insulin-Like Growth Factor-1) is a modified analogue of naturally occurring IGF-1 engineered for prolonged activity in laboratory settings. The peptide contains a substitution at the third amino acid and an extended amino acid sequence that reduces binding to IGF-binding proteins, allowing researchers to investigate IGF-1 receptor signaling over longer experimental periods.
Researchers frequently utilize IGF-1 LR3 when studying:
- Cellular proliferation
- Skeletal muscle biology
- Tissue regeneration pathways
- Protein synthesis signaling
- Glucose metabolism
- Growth factor receptor activation
- Recovery mechanisms
- Cell differentiation
