About the compound

What is DSIP?

DSIP, or Delta Sleep-Inducing Peptide, is a small nonapeptide first isolated in 1977 from the cerebral venous blood of rabbits during early sleep-research experiments. It carries CAS number 62568-57-4 and a molecular weight of 848.91. Sova supplies DSIP UK as a 5mg research vial, prepared as a lyophilised powder for controlled laboratory investigation by qualified researchers.

Structurally the peptide is a chain of nine amino acids that readily crosses biological membranes in experimental models, and it is classed among the endogenous neuropeptides. Since its discovery it has been the subject of neurochemical characterisation, with researchers mapping its amino-acid sequence, stability and interaction with central nervous system tissue across a range of in-vitro and animal models.

In the research literature DSIP is investigated primarily in the context of sleep regulation, from which it takes its name, and broader neuropeptide signalling. Laboratory work has explored its association with slow-wave electroencephalographic activity, circadian rhythm models and stress-response pathways, making it a recurring reference peptide within neuroscience and chronobiology studies.

Each batch of Sova DSIP is verified by reverse-phase HPLC for identity and purity and by ESI mass spectrometry to confirm its molecular weight, with findings recorded on a batch-linked Certificate of Analysis. Store the sealed vial cool, dry and away from light, frozen for long-term storage. This product is supplied strictly for laboratory research use only, not for human or veterinary use.

FAQ

DSIP, answered.

What is DSIP?

+

DSIP (Delta Sleep-Inducing Peptide) is a nonapeptide, a chain of nine amino acids, first isolated in 1977 during sleep studies. It carries CAS number 62568-57-4 and a molecular weight of 848.91, and Sova supplies it as a lyophilised 5mg research vial.

Is DSIP legal to buy in the UK?

+

DSIP is sold in the UK strictly as a research chemical for laboratory use only. It is not a licensed medicine, supplement or food, and it is not intended for human or veterinary administration. Buyers are responsible for compliant storage, handling and use in a research environment.

What is DSIP studied for?

+

DSIP is investigated in research for its role in sleep regulation and neuropeptide signalling. Studies have examined its relationship with slow-wave sleep activity, circadian rhythm models and stress-response pathways, and it is frequently used as a reference peptide within neuroscience and chronobiology investigations.

How is Sova's DSIP verified?

+

Sova verifies each DSIP batch using reverse-phase HPLC to confirm identity and purity, together with ESI mass spectrometry to check the molecular weight. Every result is recorded on a batch-linked Certificate of Analysis, allowing each vial to be traced to its own analytical documentation.

How should DSIP be stored?

+

Keep the lyophilised DSIP vial sealed, cool, dry and protected from light, with freezing recommended for long-term storage. After reconstitution for research purposes, store it refrigerated and limit repeated freeze-thaw cycles to help maintain the peptide's stability.

When was DSIP first discovered?

+

DSIP was first isolated in 1977 by researchers studying sleep, who recovered it from the cerebral venous blood of rabbits during electrical stimulation experiments. Its name reflects the delta-wave sleep activity observed in those early studies, and it has been investigated as a neuropeptide ever since.
