DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring nonapeptide (Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) first isolated from cerebral venous blood during induced sleep. In research it is examined as a putative neuromodulatory peptide with reported interactions with circadian, neuroendocrine and stress-response signalling, though its endogenous receptor remains incompletely characterised.

For laboratory research use only. Not for human or veterinary use.
