Frequently Asked Questions
What is DSIP?
+
DSIP (Delta Sleep-Inducing Peptide) is a 9-amino-acid neuropeptide originally isolated from rabbit cerebral venous blood. In research it is studied for sleep-architecture pathway research, hypothalamic-pituitary axis modulation, and stress-response signaling. Supplied strictly for Research Use Only.
What is DSIP used for in research?
+
DSIP is studied in preclinical research on sleep biology, EEG slow-wave activity in rodent models, cortisol pathway research, and circadian regulation. All cited studies are conducted in rodent or in-vitro systems consistent with the molecule's RUO classification.
Is DSIP an endogenous or synthetic peptide?
+
DSIP is a naturally occurring (endogenous) peptide that has been characterized in mammalian central nervous system tissue. The product supplied here is a synthetic version produced via standard solid-phase peptide synthesis with the same amino acid sequence.
What does the Certificate of Analysis verify?
