DSIP — Research Guide
DSIP (Delta Sleep-Inducing Peptide) is a nonapeptide neuromodulator originally isolated from rabbit cerebral venous blood. It is studied as a neuromodulator-class compound in receptor-binding and CNS-pathway research and is one of the most-cited nonapeptide neuromodulator references.

Chemistry & identity
DSIP (CAS 62568-57-4, MW 848.83 g/mol) has the 9-amino-acid sequence WAGGDASGE. It is a small, hydrophilic peptide that is rapidly cleared from plasma in published in-vivo research models.
Research applications
- Neuromodulator-class receptor binding studies
- CNS-pathway and neurotransmission research
- Comparative nonapeptide structure-activity work
- Short-half-life peptide PK characterization
- Cell-culture neuromodulator assays
Stability & storage
Lyophilized DSIP is stable at −20°C protected from light. Small, hydrophilic peptides benefit from immediate refrigeration after reconstitution.

FAQ
Why is the half-life so short?
Small, unmodified peptides with no fatty-acid or amino-acid-modification stabilizers are rapidly cleared from plasma in published in-vivo studies. The published plasma half-life is on the order of minutes.
What purity does Orion ship?
≥ 98.8% by reversed-phase HPLC, batch-specific value on the COA.
What's the molecular weight?
848.83 g/mol. Identity is confirmed by MS against this theoretical mass on every batch.
Is this for human use?
No. In-vitro research use only.
