IGF-1 DES 1mg is a truncated form of insulin-like growth factor-1 lacking the first three N-terminal amino acids, supplied by Peptide Sciences for growth-factor research.
IGF-1 DES(1-3) Research Overview
Removing the N-terminal tripeptide (Gly-Pro-Glu) reduces binding to IGF-binding proteins, making IGF-1 DES several times more potent than native IGF-1 in cell assays, though with a shorter duration of action than IGF-1 LR3. It occurs naturally in some tissues and is studied for local, rapid growth-factor signalling.
