DSIP (Delta Sleep-Inducing Peptide): Research Profile

DSIP (delta sleep-inducing peptide) is a nonapeptide (Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) first characterized in research on sleep-related cerebral activity. It is used as a reference compound in neuroendocrine and chronobiology research.

Research background

DSIP is notable in research settings for its membrane permeability and its role as a tool compound in studies of sleep-related and stress-related signaling.

Reported activity in research models

In animal and cell models, DSIP has been investigated in the context of sleep-pattern regulation, hypothalamic-pituitary signaling, and stress-response pathways. These observations are limited to laboratory and preclinical research settings and are not statements about outcomes in humans.

Handling and storage

Supplied as a lyophilized powder. Store lyophilized material at -20°C. Reconstitution with bacteriostatic or sterile water is common for laboratory handling; keep any reconstituted solution refrigerated and use it within the timeframe appropriate to the researcher’s protocol.

Analytical and COA

Purity is determined by HPLC and identity is confirmed by mass spectrometry. Each batch ships with a batch-specific certificate of analysis from an independent third-party laboratory; refer to the COA for lot-specific measured values. Endotoxin and sterility testing are not performed unless explicitly stated.
