IGF-1 LR3
IGF-1 LR3 (Long Arg3 Insulin-like Growth Factor-1) is a synthetic peptide analog of human IGF-1, modified to enhance stability in controlled experimental environments. This analog incorporates an arginine substitution at position 3 and an extended amino acid sequence to alter its interaction profile in receptor-binding studies. In laboratory settings, IGF-1 LR3 is utilized in research involving peptide–receptor interactions, ligand binding dynamics, and intracellular signaling pathway analysis under defined in vitro conditions. This material is supplied in lyophilized powder form and is intended strictly for in vitro research and analytical applications.
