DSIP 5mgResearch Peptide · PepC.Labs

Overview

DSIP (Delta Sleep-Inducing Peptide) is a nine-amino-acid endogenous neuropeptide first isolated in 1977 by Monnier, Schoenenberger and colleagues from the cerebral venous blood of rabbits in electrically induced slow-wave sleep. It has been investigated in published animal research for its role in delta-wave sleep architecture and stress-response pathways.

This vial contains 5mg of DSIP as a lyophilised powder for reconstitution with sterile diluent in the laboratory.

What is DSIP?

DSIP is a small endogenous peptide with the sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu. It was named for the observation that its infusion into rabbits in behavioural experiments appeared to increase the proportion of delta-wave activity on electroencephalography recordings during sleep.

Published animal research has investigated DSIP in the context of:

Mechanism of Action

The precise molecular mechanism of DSIP is still poorly characterised in the published literature. It does not appear to bind a single well-defined receptor in the way many neuropeptides do, and its central nervous system effects in animal models have been studied across multiple signalling pathways, including those involving the hypothalamic-pituitary axis.

Early pharmacokinetic work describes a short serum half-life and rapid tissue distribution, which is a central consideration in protocol design for any follow-up research.

Published Research

Selected areas of published preclinical research include:

Human clinical data is limited and largely historical. DSIP is not approved by the TGA or FDA for any therapeutic indication.

Quality and Verification

Every batch ships with a batch-specific Certificate of Analysis documenting purity by HPLC (≥99%) and mass spectrometry confirmation of peptide identity. The vial is shipped lyophilised to preserve stability during transit and should be stored at -20°C prior to reconstitution and 2-8°C after reconstitution in the laboratory.
