Description

DSIP Reference Material | Delta Sleep-Inducing Nonapeptide

DSIP (Delta Sleep-Inducing Peptide; MW 849.86 g/mol) is a nonapeptide (Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) first isolated from rabbit cerebral venous blood. As a blood-brain barrier-penetrant neuropeptide, it is used as a reference compound in sleep circuit, HPA axis, and neuroendocrine research.
