Research summary
The DSIP literature consists mostly of older animal studies and small human studies with mixed results, and the underlying biology remains unclear. This summary describes what the literature has investigated. It is not a claim about the effects of our product, which is supplied for laboratory research only.
Mechanism of action
DSIP (delta sleep-inducing peptide) is a nonapeptide first isolated from the cerebral blood of rabbits during induced sleep. Its receptor and precise mechanism have not been clearly established. Published work has examined effects on sleep architecture, stress responses and neuroendocrine signalling in animal models.
Chemical properties
Sequence: Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu (9 residues). Molecular weight: approx. 849 g/mol. Form: lyophilised powder. Purity and identity: see the batch Certificate of Analysis (HPLC and mass spectrometry).
Storage and handling
Supplied as a lyophilised (freeze-dried) powder. Store sealed, cold, dry and protected from light, as stated on the Certificate of Analysis and product label. Allow the vial to reach room temperature before opening to limit condensation. Avoid repeated temperature cycling and humidity exposure. For laboratory research use only.
