IGF-1 LR3 (Long R3 Insulin-like Growth Factor-1) is a modified, long-acting analog of IGF-1. The modifications extend its half-life and reduce its binding to IGF-binding proteins, which is why it is a frequent tool in research on cell growth, proliferation, and the IGF-1 signaling pathway. It is studied in models of muscle-cell development, nutrient partitioning, and cellular growth mechanisms.
Peptides Optimized IGF-1 LR3 is independently HPLC tested to 99% purity with a Certificate of Analysis available per batch. Supplied lyophilized and shipped with appropriate temperature handling.
