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?

≥99% by reverse-phase HPLC with LC-MS/MS confirming the 848.8 Da mass, LAL endotoxin testing, and visual QC. Independent third-party testing with a batch-specific Certificate of Analysis per lot.

Where is the Certificate of Analysis for DSIP?

On this page and in the Peptide.Express lab results library. Each CoA is batch-specific and lists HPLC purity, LC-MS/MS mass confirmation, endotoxin result, testing laboratory and test date.

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.
