DSIP Nasal Spray
Pre-mixed delta sleep-inducing peptide solution in a metered 15 mL or 30 mL bottle
- FormPre-mixed aqueous solution in a bottle fitted with a metered spray pump
- Mol. weight848.81 g/mol
Supplied for laboratory research use only. Not for human or veterinary use, and not intended to diagnose, treat, cure or prevent any disease.
Overview
This product supplies delta sleep-inducing peptide as a ready-to-dispense aqueous solution in a metered spray bottle rather than as a lyophilized powder requiring reconstitution. The molecule is identical to our vialed DSIP: the nonapeptide Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu, first isolated from rabbit cerebral venous blood during slow-wave sleep and studied since as an endogenous neuromodulatory peptide.

Questions about DSIP Nasal Spray
How does this differ from the DSIP vial?
The peptide is the same nonapeptide with the same specifications. The difference is format: this is a pre-mixed aqueous solution in a metered spray bottle, ready to dispense, while the vial is a lyophilized powder the laboratory reconstitutes itself before use.
How much solution does one actuation deliver?
The metered pump delivers approximately 0.1 mL per actuation, which works out to roughly 150 actuations from a 15 mL bottle. Actual delivered volume depends on priming state and actuation technique, so studies that depend on it normally verify gravimetrically.
Why is refrigerated storage required?
Peptides in solution degrade faster than lyophilized powder. DSIP's aspartate-glycine motif is susceptible to deamidation and isomerisation in water, and its tryptophan residue is prone to oxidation and photodegradation. Cold, dark, upright storage slows all three processes.
What documentation is available?
The peptide raw material is third-party HPLC tested to at least 99% purity, and a lot-matched certificate of analysis is available covering identity, purity and the concentration of the filled solution. Retain it with your study record for traceability.
Can the solution be used in assays other than nasal delivery work?
It can, but the solution contains formulation excipients that a reconstituted vial does not, and those can interfere with chromatography and certain assay chemistries. For non-delivery work, the lyophilized vial is usually the cleaner starting material.
