DSIP — delta sleep-inducing peptide — is a small neuropeptide that has been a subject of neuroscience and chronobiology research since it was first described in the 1970s. This overview covers what DSIP is, how it appears in the research literature, and how to source a well-characterized reference standard for laboratory work.
What is DSIP?
DSIP is a nonapeptide (a chain of nine amino acids) originally isolated from cerebral venous blood in early sleep-physiology research. It is studied as an endogenous regulatory peptide and is frequently used in laboratory models that investigate neuropeptide signaling. As a research material it is supplied as a lyophilized (freeze-dried) powder and reconstituted with a laboratory diluent such as bacteriostatic water before use in a research model.
Research background
DSIP appears across the neuroscience literature in the context of sleep architecture, stress-response, and neuromodulation research models. Investigators typically characterize its identity, purity, and biochemical behavior in vitro and in non-clinical settings. Because DSIP is an endogenous peptide, it is also used as a reference compound in assay development. Peptide Technologies makes no claims about outcomes in humans or animals; DSIP is offered only for that laboratory research context.
Purity and verification
For laboratory research, the value of a DSIP reference standard is in its documentation. Every batch we supply is analyzed by an independent, accredited US laboratory and ships with a batch-specific Certificate of Analysis (COA) confirming identity and purity by HPLC. The certificate is QR-linked to the vial so the exact lot can be verified before and after purchase.
Sourcing DSIP for research
You can source a COA-verified DSIP reference standard from our catalog: see DSIP 5mg for the current batch certificate and specifications, browse the full research peptides category, or review how we document quality on the verified peptides page. For reconstitution supplies, see our liquids, aminos & solvents category.
FAQ
What is DSIP?
DSIP (delta sleep-inducing peptide) is a nonapeptide studied in neuroscience and chronobiology research. It is supplied as a lyophilized reference material for laboratory research use only — not for use in humans or animals.
Is DSIP third-party tested?
Yes. Each batch ships with a QR-linked, batch-specific Certificate of Analysis from an independent accredited US laboratory confirming identity and HPLC purity.
Where can I buy DSIP for research?
You can buy COA-verified DSIP online from Peptide Technologies at peptidetech.is. See the DSIP product page for the current certificate. Supplied for laboratory research use only.
How is DSIP stored?
As a lyophilized peptide it is generally kept cold and protected from light until reconstitution with a laboratory diluent. Handling guidance is intended for laboratory use only.
