About DSIP

DSIP (delta sleep-inducing peptide) is a nonapeptide first characterized in neuroscience research examining delta-wave sleep activity in preclinical models.

Research interest centers on its interaction with neuroendocrine signaling, circadian rhythm modeling, and stress-response pathway investigation in laboratory systems.

This lot is inbound; the listing is published now for reference and will be marked in stock once the shipment arrives and independent testing clears.

Research Areas

  • Sleep architecture models
  • Circadian rhythm research
  • Neuroendocrine signaling
  • Stress-response pathway studies

Storage & Handling

  • Store lyophilized vials at -20°C for long-term laboratory storage; short-term storage at 2–8°C is acceptable for materials in active use.
  • Protect vials from light and repeated freeze-thaw cycles; aliquot before freezing where practical.
  • Once a vial has been opened in a laboratory setting, use within the timeframe recommended by your institution's SOPs and document handling in your lab notebook.
  • Keep sealed vials in a desiccated environment; humidity exposure can degrade lyophilized peptide material over time.

Testing & Quality

Each lot undergoes independent third-party HPLC/MS analysis. A lot-specific Certificate of Analysis is available on request.

Learn more about our sourcing and testing process on our Testing & Quality page.

Shipping & Returns

Free U.S. shipping on orders over $200; otherwise a flat $9.99 shipping rate applies. All sales are final. See our full Shipping & Returns policy for details.
