DSIP
DSIP (delta sleep-inducing peptide) is a naturally occurring linear nonapeptide first isolated from the cerebral blood of rabbits. It belongs to the neuropeptide class, and its unmodified chain has free amino and carboxyl termini. PeptXBio supplies it as a lyophilised powder, ready for laboratory research.
Quality and purity
≥99% purity (HPLC). High-grade laboratory lyophilised powder, analytically verified and produced in consistent batches so that research results are reproducible.
Specifications
- CAS number: 62568-57-4
- Molecular formula: C35H48N10O15
- Molecular weight: 848.81 g/mol
- Amino acid sequence: Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu (WAGGDASGE)
- Peptide chain: 9 amino acids
Why it is studied
DSIP is studied as an endogenous neuromodulator linked to the mechanisms that regulate sleep architecture and circadian rhythm in cellular and animal brain models. Laboratory work examines its possible effects on neuroendocrine axes, stress-response markers and neurotransmitter systems. Its distribution and stability in biological media in vitro are also studied. This information is provided for research context only and is not an instruction for use.
Reconstitution
For laboratory work, the lyophilised powder is dissolved in bacteriostatic water by swirling the vial slowly and gently until a clear solution forms – it should not be shaken. The prepared stock solution is kept refrigerated and used according to the research protocol. These directions cover only the preparation of the material in the laboratory.
What you get
- Active substance: DSIP (delta sleep-inducing peptide)
- Form: lyophilised powder
- Amount per vial: 10 mg
- Solvent (sold separately): bacteriostatic water
Storage
Keep the unopened vial in a refrigerator (2–8 °C), or in a freezer (−20 °C) for longer storage, protected from light. Once reconstituted in bacteriostatic water, keep it refrigerated and use it within the time set out in your research protocol.
Important
For in vitro scientific research only. Not for use on humans or animals; this is not a medicine, dietary supplement or cosmetic product.
Frequently asked questions
DSIP (Delta Sleep-Inducing Peptide) is a nine-amino-acid neuropeptide. In scientific research it is studied for its possible effect on the regulation of the sleep–wake cycle, interacting with opioid receptors and modulating the neuroendocrine system.
DSIP is studied for its effects on the deep (delta) sleep phase, on the secretion of the stress hormone cortisol and on somatotropin production. It is used in experiments investigating the mechanisms of sleep disorders and the stress response.
Our DSIP is a lyophilised (freeze-dried) powder supplied in 10 mg vials.
Vials must be kept in a refrigerator at +2 °C to +8 °C, protected from light. The reconstituted solution is used within 7 days.
Absolutely not. This product is sold exclusively for laboratory research and scientific experiments. It is not intended for human consumption or for the diagnosis or treatment of disease.
