IGF-1 LR3 (Insulin-Like Growth Factor-1 Long Arg³) is a synthetic long-acting analog of insulin-like growth factor-1 (IGF-1), modified with an arginine substitution and extended peptide sequence to enhance stability and receptor activity. It is widely studied for its interaction with IGF-1 receptors involved in cellular growth, differentiation, and metabolic signaling across multiple pre-clinical research models. Researchers investigate IGF-1 LR3 for its potential roles in cell proliferation pathways, protein synthesis signaling, tissue growth mechanisms, and metabolic regulation in controlled laboratory and experimental studies. For Laboratory and Scientific Research Use Only. Not for Human Consumption. Why Researchers Choose IGF-1 LR3 IGF-1 Receptor Activation IGF-1 LR3 has been shown in pre-clinical research to bind IGF-1 receptors with reduced affinity for IGF-binding proteins, resulting in prolonged receptor interaction and sustained downstream signaling. Cellular Growth & Proliferation Research Evaluated in cell culture and tissue models to study mechanisms related to cell division, differentiation, and growth factor-mediated signaling pathways. Protein Synthesis & Metabolic Signaling Investigated for its role in anabolic signaling cascades associated with nutrient utilization, glucose metabolism, and cellular energy balance. Tissue & Regenerative Research Applications Studied in pre-clinical models examining tissue growth, repair signaling, and growth factor-driven cellular responses. High Purity Assurance Batch-verified at ≥98% purity using HPLC and Mass Spectrometry testing. Important Note For laboratory and scientific research only. Not for human consumption, therapeutic, or diagnostic use.
