Delta Sleep-Inducing Peptide (DSIP)

$1,167.00

    Catalog Number: MDP0402 (5 mg)

    Delta Sleep‑Inducing Peptide (DSIP) is a high‑purity synthetic nonapeptide widely used as a molecular tool in neuroendocrine, biochemical, and peptide‑signaling research. Originally identified in hypothalamic extracts, DSIP has been studied for its roles in neurochemical regulation, peptide–receptor interactions, and hypothalamic signaling pathways. Its defined sequence and stable lyophilized format support reproducible performance across biochemical, neurochemical, and immunological workflows. Custom bulk amounts of this product are available upon request.

    Products are for in vitro research use only (RUO).

Scientific Overview

Delta Sleep‑Inducing Peptide (DSIP) is a nonapeptide originally isolated from the hypothalamus and investigated for its role in neuroendocrine regulation. Although its physiological function remains incompletely defined, DSIP has been studied in contexts involving sleep‑associated neurochemistry, hypothalamic signaling, stress responses, and peptide–hormone interactions. Its small size and well‑characterized sequence make DSIP a useful molecular tool for biochemical, neurochemical, and receptor‑level research.

Common Research Applications

  • Neuroendocrine pathway studies
  • Peptide–receptor interaction research
  • Biochemical assays involving hypothalamic peptides
  • Investigations of peptide stability and delivery systems
  • Cell‑based assays exploring peptide‑mediated signaling (RUO)
  • Neurochemical method development and peptide quantification

Usage & Handling Guidance

This product is supplied as a lyophilized powder. For experimental use, reconstitute in sterile water, dilute acetic acid, or assay‑compatible buffer. DSIP is sensitive to repeated freeze–thaw cycles; aliquot solutions immediately after preparation and store at −20°C or below.

  • Reconstitution: Sterile water, dilute acetic acid, or buffer
  • Storage: −20°C (powder and solutions)
  • Avoid: repeated freeze–thaw cycles and prolonged exposure to room temperature

What You Get

  • 5 mg synthetic Delta Sleep‑Inducing Peptide (DSIP)
  • High‑purity biotechnology‑grade peptide
  • Stable lyophilized format
  • For research use only (RUO)

Frequently Asked Questions

  • Is this product suitable for clinical or therapeutic use? No. This product is for research use only and is not intended for human or animal administration.
  • Is DSIP naturally occurring? Yes. DSIP was originally isolated from the hypothalamus, but this product is a synthetic peptide.
  • Can I obtain a COA or TDS? Documentation availability depends on the active batch. Please contact us to request COA/TDS for the lot being shipped.
  • Can this peptide be used in neurochemical assays? Yes. DSIP is commonly used in biochemical and neuroendocrine research workflows.
