Description
DSIP (Delta Sleep-Inducing Peptide) is a synthetic 9-amino acid neuropeptide originally isolated from rabbit cerebral venous blood during induced delta sleep. It is supplied as a lyophilized powder for in vitro research applications involving neuropeptide signalling, sleep-regulatory pathway biology, and opioid receptor pharmacology.

Research Context
DSIP was first characterized in the 1970s by Monnier et al. and has since been the subject of extensive preclinical research. Documented in vitro applications include opioid receptor binding studies, neuropeptide interaction assays, hypothalamic signalling pathway research, and stress-response modelling. Research teams investigating neuroendocrine peptide signalling and sleep-regulatory neuropeptide pharmacology use DSIP as a reference compound for delta wave–associated pathway studies.
