IGF-1 LR3 1mg

IGF-1 LR3 (Long R3 Insulin-like Growth Factor-1) is a synthetic analog of human Insulin-like Growth Factor-1 modified with two structural changes from native IGF-1: an arginine substitution at position 3 and an N-terminal extension of 13 amino acids. These modifications significantly extend the peptide’s half-life and reduce binding affinity to IGF-binding proteins compared to native IGF-1. As a research peptide, IGF-1 LR3 has been studied in cellular biology and biochemical research literature examining IGF receptor pharmacology and peptide stability engineering.
