DSIP

DSIP (Delta Sleep-Inducing Peptide) is a synthetic nonapeptide with the sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu. Preclinical research has investigated DSIP in experimental models involving sleep architecture, sleep-wake regulation, stress responses, neuroendocrine signaling, and neuroprotection.

This DSIP research peptide is supplied as a lyophilized powder with ≥99% HPLC purity. Its defined sequence, molecular specifications, and storage requirements make it suitable for laboratory researchers studying peptide-mediated effects on sleep-related and neurobiological pathways.

What is DSIP?

DSIP, short for Delta Sleep-Inducing Peptide, is a nine-amino-acid peptide that has been investigated primarily in experimental sleep and neuroscience research.

The supplied sequence is:

Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu

Research has explored DSIP in relation to sleep patterns, stress responses, neuroendocrine regulation, and neural protection. Experimental findings vary by model and study design, so these research observations should not be interpreted as evidence of an established clinical effect in humans.

DSIP is also known by the synonym Emideltide.

What is DSIP studied for?

DSIP has a research history spanning several areas of experimental neuroscience.

Sleep research

DSIP is investigated in relation to sleep architecture and sleep-wake cycles, including experimental models examining delta-wave or slow-wave sleep patterns.

Its name comes from its historical association with sleep research, but the term “sleep-inducing” should be understood as a description of the research subject rather than a claim of a predictable effect in humans.

Stress and neuroendocrine research

Researchers have examined DSIP in models involving stress responses and neuroendocrine signaling. Studies investigate how peptide activity may interact with physiological responses associated with stress.

Neuroprotection research

Experimental research has also explored DSIP in models involving neural injury and cellular stress, including investigations into potential neuroprotective mechanisms.

Neurological research

DSIP has been examined in experimental models involving neurological activity, including research related to seizure and brain-response pathways.

All of these areas are research applications. They do not establish DSIP as a treatment for insomnia, anxiety, epilepsy, brain injury, or other medical conditions.

What makes DSIP different?

DSIP has a defined nine-amino-acid structure and is specifically associated with experimental research into sleep and neurobiological regulation.

Its sequence is:

Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu

The material is specified at ≥99% HPLC purity and supplied in lyophilized form. These characteristics provide researchers with clear molecular and analytical information when comparing DSIP materials for laboratory studies.

Storage and handling

The supplied specifications indicate −20°C (−4°F) for long-term storage and 2–8°C (36–46°F) after reconstitution.

Bacteriostatic water for laboratory use is listed as the reconstitution solvent.

Researchers should follow the applicable product documentation and established laboratory procedures when preparing, storing, and handling DSIP. Specific preparation conditions should be determined by the requirements of the research protocol.

What should researchers know before ordering DSIP?

If you are comparing a DSIP peptide supplier or looking to buy DSIP online for laboratory research, review the product's molecular identity and analytical specifications before ordering.

Important product details include:

• Sequence: Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu
• CAS number: 62568-57-4
• Molecular formula: C35H48N10O15
• Molar mass: 848.83 g/mol
