DSIP
DSIP Peptide (Delta Sleep-Inducing Peptide) is a synthetic nonapeptide with the sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu and a molecular weight of approximately 849 Da. Originally isolated in 1977 from rabbit cerebral venous blood, DSIP has been extensively investigated in preclinical research focused on sleep regulation, delta-wave sleep architecture, and physiological stress adaptation.
Laboratory studies continue to explore DSIP’s potential influence on HPA axis activity, pain perception, neuroendocrine signaling, and neuroprotective pathways in models of cerebral ischemia. Researchers are particularly interested in its interactions with GABA and NMDA receptor systems, although the precise endogenous receptor and biosynthetic mechanism remain under active scientific investigation.
Ceritide Research offers DSIP (Delta Sleep-Inducing Peptide) as a premium 10mg lyophilized research peptide with verified ≥99% purity confirmed by independent HPLC and mass spectrometry. Supplied in a sterile vial and ready for immediate reconstitution per your protocol, this product delivers the reliability top research labs demand.

Peptide Storage Guidelines: Best Practices for Research Stability
At Ceritide Research, we provide high-purity peptides for laboratory and scientific research. Proper storage preserves peptide integrity and supports reliable experimental results.
Storage Guidelines for Lyophilized (Powder) Peptides
- Long-Term Storage: Keep at -20°C (-4°F) or lower (ideally -80°C / -112°F) for multi-year stability.
- Short-Term Storage: Refrigerate at 2–8°C (36–46°F) for weeks to a few months. Minimize room temperature exposure.
- Best Practices: Store in airtight vials with desiccants. Allow vials to reach room temperature in a desiccator before opening. Protect from light and moisture. Aliquot to reduce freeze-thaw cycles.
Storage Guidelines for Reconstituted Peptide Solutions
Once dissolved, peptides are less stable and should be used promptly:
- Recommended Temperature: Store at 2–8°C (36–46°F) (refrigerator) for short-term use, typically up to 1–4 weeks depending on the sequence and buffer.
- Longer-Term Solution Storage: Aliquot and freeze at -20°C (-4°F) or lower. Avoid storing solutions long-term when possible.
- Best Practices: Use sterile techniques, bacteriostatic water or research-grade buffers, and minimize exposure to air and light. Prevent repeated freeze-thaw cycles.
For Research Use Only
