DSIP Overview
DSIP is a small amphiphilic peptide consisting of nine amino acids (Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) with demonstrated effects on circadian signaling and neuroendocrine regulation in experimental models. Originally identified through its ability to modulate delta-wave patterns in experimental systems, DSIP has been studied for its influence on circadian rhythms, electroencephalographic patterns, and hypothalamic-pituitary-adrenal (HPA) axis activity. Research indicates potential modulatory effects on GABAergic and serotonergic signaling systems, corticosterone and ACTH dynamics, and oxidative stress responses in laboratory settings.
Schoenenberger et al. (1977).
History
DSIP was first isolated in 1977 by Monnier, Schoenenberger, and colleagues from the cerebral venous blood of rabbits during slow-wave induction experiments. Initial studies demonstrated that intraventricular administration of this peptide promoted delta-frequency EEG patterns consistent with slow-wave activity. Since its discovery, DSIP has been investigated across neuroscience, endocrinology, and circadian research disciplines for its diverse neuromodulatory properties.

Each vial contains the labelled quantity of lyophilized peptide. The stated milligram figure refers to the peptide content, not the total mass of the lyophilized cake.
Reconstitution requires bacteriostatic water and appropriate laboratory equipment, which are not included.
Products ship as research materials without directions for use. Handling should follow your own laboratory protocols.
Store lyophilized material at 2-8°C and away from light. Once reconstituted, follow your laboratory's stability guidance.
