Research Context

Research Overview

Delta Sleep-Inducing Peptide (DSIP) is a synthetic nonapeptide with the sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu. CAS 62568-57-4, molecular formula C₃₅H₄₈N₁₀O₁₅, molecular weight 848.86 g/mol. It was first isolated from the cerebral venous blood of rabbits in 1977 by Monnier and colleagues following thalamic stimulation.

DSIP does not appear to interact with a single identified receptor but has been shown to modulate multiple neuroendocrine systems in research models, including corticotroph regulation, hypothalamic-pituitary-adrenal axis signaling, and GABA and opioid receptor systems. Research applications include studies of neuropeptide interactions with stress response pathways, circadian rhythm models, and multi-receptor pharmacology. It is also used as a reference compound in neuroendocrine peptide characterization studies.

Supplied as a lyophilized powder. Each lot is independently tested by HPLC-UV with a minimum purity threshold of ≥99.0%. Molecular identity confirmed by LC-MS prior to release. Certificate of Analysis available for every lot number.

For laboratory and in-vitro research use only. Not for human or veterinary use. Not FDA approved.

Yes. Every lot is tested by an independent third-party laboratory using HPLC-UV before it is released for sale, and results are published in the COA Library.

How do I locate my lot's Certificate of Analysis?

Use the "View Certificate of Analysis" link on this page, or search the COA Library directly by compound name or the lot number printed on your vial label.

What analytical methods are used?

Purity is determined by HPLC-UV. Molecular identity is confirmed by LC-MS prior to release.

How is the material packaged?

Material ships in a tamper-evident, lot-labeled vial inside cold-chain packaging appropriate for the season.

What does "Research Use Only" mean?

This product is sold exclusively for laboratory and in-vitro research applications by qualified researchers. It is not a drug, dietary supplement, or approved for human or veterinary use.
