DSIP (Delta Sleep-Inducing Peptide) is a nine amino acid neuropeptide, first isolated from rabbit brain tissue in the 1970s during work on sleep signalling. In research it is best known for its association with slow-wave sleep and delta EEG activity.
DSIP is studied for how it crosses the blood-brain barrier and interacts with central nervous system signalling, circadian timing and the stress axis, which keeps it in use across neuroscience research models (Schoenenberger & Monnier, 1977, PNAS).
Research Applications
- Studied in models of sleep architecture and delta wave activity
- Relevant in research on circadian rhythm and timing
- Examined in stress response and corticotropin research models
- Applied in blood-brain barrier transport studies
Available in 5 mg and 10 mg vials at ≥99% HPLC purity.
Supplied as a lyophilized powder for stability.
