What is DSIP (Delta Sleep-Inducing Peptide)?

A synthetic nine-amino-acid neuropeptide first isolated from rabbit blood, also known as delta sleep-inducing peptide, DSIP is studied in sleep and circadian research. Research focuses on its presence across brain regions and its overlap with several hormone systems.

  • Studied for its role in sleep and circadian research models.
  • Investigated for its distribution across multiple brain regions.
  • Examined for its overlap with several hormone systems.
  • Used as a research tool to study sleep-wake and stress signalling.

For research use only. Not intended for human use.

First isolated from cerebral venous blood during slow-wave sleep research in the 1970s, Delta Sleep-Inducing Peptide remains one of the most structurally distinctive nonapeptides in chronobiology and neuroendocrine research. DSIP (CAS 62568-57-4) carries the molecular formula C35H48N10O15 and a molecular weight of 848.82 g/mol. Its sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu is notable for the absence of an identified cognate receptor. Produced via solid-phase peptide synthesis.

In vitro electrophysiology studies using cortical and thalamic slice preparations have investigated whether Delta Sleep-Inducing Peptide modulates GABAergic and glutamatergic synaptic transmission. In vivo rodent models have explored the compound's influence on circadian clock gene expression in the suprachiasmatic nucleus, examining whether exogenous DSIP administration alters Per and Cry transcription rhythms.

Manufactured in a quality-controlled laboratory to a guaranteed purity of 98% or above. Every batch undergoes independent third-party testing using HPLC and MS-UPLC analysis before dispatch. Vials are vacuum sealed and stored in a temperature-controlled, monitored cold storage system. A batch-specific Certificate of Analysis is available on request.

Sold strictly for in vitro research purposes only. Not for human consumption. Intended for use by qualified researchers in laboratory settings only.
