Overview+

Delta Sleep-Inducing Peptide is a naturally occurring neuropeptide studied for its role in sleep regulation and stress-response pathways. It is used in research examining circadian and neuroendocrine signaling, and it is notable for its ability to cross the blood-brain barrier.

History+

First isolated in 1977 from the cerebral venous blood of rabbits during induced sleep, DSIP was characterized as an amphiphilic neuropeptide capable of crossing the blood-brain barrier. Early work focused on its association with delta-wave activity during sleep, and later research broadened into its circadian and neuroendocrine roles.

Research findings+

DSIP has been examined in neurological and endocrine models for slow-wave-sleep modulation, circadian-rhythm correlation, hormone and neurotransmitter effects, and stress-response signaling. Its association with sleep architecture, combined with the ability to cross the blood-brain barrier, is what makes DSIP a distinctive research tool for central signaling. Studies treat it as a probe linking sleep, circadian rhythm, and stress-response pathways in laboratory models.

Key areas of research
  • →Neurological: Sleep architecture, delta-wave activity
  • →Endocrine: Circadian and hormonal signaling
  • →Systemic: Stress-response and blood-brain-barrier transport

Frequently asked questions

What's the actual amount in each vial?+
Each vial contains the labeled mass of lyophilized peptide. Selected sizes appear above the price.
Are additional supplies needed?+
Reconstitution requires bacteriostatic water and appropriate sterile research labware – not included.
How long does a vial last?+
Sealed lyophilized vials are stable at −20°C for 24 months. Once reconstituted, store at 2–8°C and use within 28 days.
Does the product come with instructions?+
Each shipment includes the batch-specific Certificate of Analysis and recommended handling protocol.
What purity level is guaranteed?+
≥ 99% by reverse-phase HPLC (UV-220nm), confirmed via ESI-TOF mass spectrometry.
How should I store these products?+
Store sealed vials at −20°C, protected from light. Reconstituted solutions at 2–8°C.
What are peptides and how do they work?+
Peptides are short chains of amino acids that occur naturally in organisms, where they act as messengers in many biological systems. While some peptides have been developed for medical use, laboratory research focuses on understanding their activity at the cellular level, examining how they impact essential processes in vitro.
Do these products come with instructions?+
Products from Fast Track Labs are supplied without usage instructions, as they are designated solely for in vitro laboratory research and prohibited by law for human or animal consumption. Any misuse or unlawful application of these products will result in permanent denial of service.
How long do products take to deliver?+
Orders are typically processed and shipped within 24 hours, Monday through Saturday. Delivery times vary by location, but most domestic orders arrive within 3–5 business days. You'll receive tracking information as soon as your order ships.
