Research-Grade Compound

DSIP (delta sleep-inducing peptide) is an endogenous nonapeptide with the sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu (WAGGDASGE), first isolated in 1977 from the cerebral venous blood of rabbits undergoing induced slow-wave sleep. Molecular formula C35H48N10O15, molecular weight 848.8 Da, CAS 62568-57-4.

Purity standard: DSIP is sourced to ≥99% by HPLC — sourcing spec. That is the specification every batch must meet, not a measurement of any one vial — the measured figure for a batch is on that batch's Certificate of Analysis.

Buying DSIP — Frequently Asked Questions

What purity standard and testing does Peptide.Express apply to DSIP?

Sourced to a ≥99% HPLC specification. Where a certificate is on file, compare a reported mass with 848.8 Da. Endotoxin and visual lines appear only when the laboratory reported them.

Where is the Certificate of Analysis for DSIP?

On this page and in the Peptide.Express lab results library. Sourced against a ≥99% HPLC purity specification. Third-party Certificates of Analysis are published where on file.

How should DSIP be stored before and after reconstitution?

Lyophilized: -20°C, desiccated and protected from light, stable for 24 months from manufacture. Reconstituted: 2–8°C, light-protected, used within 14–28 days. Do not freeze the reconstituted solution.
