IGF-1LR3, short for Insulin-Like Growth Factor-1 Long R3, is a highly specialized, long-acting analogue of naturally occurring IGF-1, designed primarily for scientific research applications. Unlike endogenous IGF-1, its modified structure (featuring an arginine substitution at position 3 and an 8-amino-acid extension) extends its half-life to 2–3 times longer, eliminating the need for frequent administration in lab settings.

This research-grade compound exhibits exceptional bioactivity, with high binding affinity to IGF-1 receptors—supporting studies on cell proliferation, tissue repair mechanisms, and metabolic regulation. It is widely used in in vitro cell culture and preclinical research to explore growth factor signaling pathways, making it a valuable tool for biotech labs, academic institutions, and pharmaceutical R&D teams.

Our IGF-1LR3 adheres to strict production standards, ensuring high purity (>99%) and batch-to-batch consistency. For detailed COA, storage guidelines, or custom bulk orders, contact us.
