Compound Overview
Delta Sleep-Inducing Peptide (DSIP) is a naturally occurring 9-amino acid neuropeptide originally isolated from rabbit brain venous blood. Laboratory research examines its interactions with sleep-wake cycle regulation, stress response modulation, neuroendocrine signaling, and cortisol/ACTH pathway modulation.
Research Background & Published Literature
DSIP has appeared in sleep physiology and stress response research literature since the 1970s. Studies published in Peptides, Neuroscience Letters, and related journals have evaluated delta wave sleep patterns, CRH signaling, and hypothalamic-pituitary-adrenal (HPA) axis regulation in controlled research contexts.

Storage, Handling & Stability Guidelines
Use the applicable lot/source record for storage of unopened material. Any diluent selection, preparation, temperature, aliquoting, or post-reconstitution hold conditions must be established by a qualified laboratory under a validated SOP; this page does not establish a stability window.
- Keep ambient-temperature handling time as short as practical to support compound integrity.
- Reseal vials promptly after each withdrawal to limit moisture exposure.
- Use appropriate personal protective equipment and follow institutional chemical safety protocols at all times.
- For traceability, label all aliquots with compound name, concentration, reconstitution date, and operator initials.
Quality Assurance & Lab Verification
A finalized public Certificate of Analysis is available for this catalog item. Review the public COA for the applicable lot. Lot-specific identifiers, assay values, and methods are maintained in that record and are not repeated in this product dossier.
Shipping
Orders ship within the United States via USPS; international orders are not accepted. Laboratories should follow their validated SOP together with any handling fields published for the represented product or lot; no universal prepared-solution condition is inferred here.

Research context.
DSIP has been studied since the 1970s in sleep physiology and stress response research. Published studies in Peptides, Neuroscience Letters, and other journals have examined its effects on delta wave sleep patterns, CRH signaling, and hypothalamic-pituitary-adrenal (HPA) axis regulation.
Verification standard.
Certificate information is lot-specific. A finalized public record shows only the methods, fields, and results present for that named lot. A pending certificate state exposes no assay values and must not be interpreted as analytical verification. Review Nexus lab verification.
