IGF-1 DES, also known as Des(1-3)IGF-1, is a truncated insulin-like growth factor-1 analogue lacking the first three N-terminal residues, giving it reduced affinity for IGF-binding proteins, studied in growth research. It is supplied as a high-purity white lyophilized powder at >=99% HPLC purity in sealed vials.

IGF-1 DES, also known as Des(1-3)IGF-1, is a truncated insulin-like growth factor-1 analogue that lacks the first three N-terminal residues, resulting in reduced affinity for IGF-binding proteins and making it a subject of growth research. It is supplied as a high-purity white lyophilized powder with >=99% HPLC purity in sealed vials.

 IGF-1 DES is investigated in research on cell growth and protein synthesis, and is commonly applied in cell-culture and preclinical studies. As a modified research peptide, it does not carry a single unified CAS number. The des(1-3) variant shows high receptor affinity with minimal binding-protein interference, providing a tool for studying insulin-like-growth-factor receptor activation dynamics. Investigators use it in muscle and growth-factor signaling research. The lyophilized powder is supplied with documented purity and handling guidance. The truncated form offers a distinct pharmacological window for receptor studies, and investigators frequently compare its potency with full-length and long-acting variants. The lyophilized material is suitable for receptor-binding and signaling assays, and batch documentation supports reproducible use in academic and industrial laboratories.
