DSIP (Lyophilised)

Product & Research Profile
DSIP, or Delta Sleep-Inducing Peptide, is a synthetic nonapeptide composed of nine amino acids with the sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu (WAGGDASGE).

DSIP was originally characterised through laboratory research examining delta-wave EEG activity, which led to its name. Subsequent research has explored the peptide across neuropeptide signalling, sleep-associated experimental models and stress-related biological pathways, although its precise endogenous role and receptor mechanism remain unresolved.

That uncertainty makes DSIP particularly interesting as a research compound. Its defined nine-amino-acid structure allows investigation of peptide structure–activity relationships, sequence specificity, peptide stability and the molecular mechanisms associated with neuropeptide signalling.

DSIP is also useful for analytical characterisation and comparative research involving related peptide fragments and modified analogues, allowing researchers to examine how changes to its short peptide sequence influence biological and molecular behaviour.

Supplied as a lyophilised powder in sealed laboratory vials, DSIP is available in 5mg and 10mg quantities for research and analytical applications.
