IGF-1 LR3 (Long Arg³ Insulin-Like Growth Factor-1) is a modified analog of native IGF-1 engineered to provide an extended half-life and reduced binding to IGF-binding proteins. In research settings, IGF-1 LR3 is studied for its role in cellular growth signaling, protein synthesis pathways, and tissue development mechanisms. The LR3 modification allows for prolonged receptor interaction, making it a widely researched compound in cell biology and metabolic studies.
