DSIP Nasal Spray

Direct Anti Peptide offers DSIP Nasal Spray — a delta sleep-inducing peptide (DSIP) formulation manufactured to ≥98% purity and supplied exclusively for in-vitro and laboratory research applications. This product is ideal for scientists investigating neuropeptide activity, sleep-cycle regulation, and hypothalamic receptor interactions. For research use only. Not for human or veterinary use. Not for clinical, diagnostic, or consumptive applications.

Product Overview

DSIP Nasal Spray from Direct Anti Peptide delivers delta sleep-inducing peptide in a precisely dosed intranasal format, purpose-built for controlled laboratory research. Delta sleep-inducing peptide is a naturally occurring neuropeptide first isolated from rabbit cerebral venous blood and has since attracted significant scientific attention for its apparent role in sleep architecture modulation, neuroendocrine signaling, and central nervous system receptor activity. Researchers studying sleep latency, sleep efficiency, and total sleep duration have found DSIP to be a compelling subject of investigation. This nasal spray format is designed to support consistent peptide delivery in experimental settings, making it a valuable tool for sleep science laboratories seeking reliable, high-purity research reagents available to buy online at competitive pricing.

Peptide Structure & Amino Acid Sequence

Delta sleep-inducing peptide (DSIP) is a nonapeptide — a short-chain peptide composed of nine amino acid residues. Its established sequence is Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu, giving it a molecular formula of C₃₅H₄₈N₁₀O₁₅ and an approximate molecular weight of 848.8 g/mol. The peptide’s relatively small size and amphiphilic character are thought to contribute to its ability to cross biological barriers in experimental models, which is one reason the intranasal delivery format is of particular interest to researchers exploring cerebrospinal fluid dynamics and hypothalamic access in laboratory settings.

Purity & Analytical Verification (HPLC & MS)

Every batch of DSIP Nasal Spray supplied by Direct Anti Peptide undergoes rigorous analytical testing to confirm a minimum purity of ≥98%. High-performance liquid chromatography (HPLC) is used to quantify peptide content and detect any residual impurities, while mass spectrometry (MS) confirms correct molecular identity and sequence integrity. Certificates of Analysis (CoA) reflecting these results are available upon request, providing researchers with the documentation required for experimental reproducibility and laboratory audit trails. Ordering from Direct Anti Peptide means you receive a fully verified research reagent backed by transparent analytical data.

Quality Control & Lyophilization Integrity

While DSIP Nasal Spray is supplied in a ready-to-use aqueous format rather than lyophilized powder, the same stringent quality control standards apply. Each production lot is assessed for sterile filtration integrity, pH consistency, osmolality, and particulate absence. Metered-dose actuators are tested for spray uniformity and dose accuracy, ensuring that each actuation delivers a consistent volume of peptide solution. This level of quality assurance supports the reproducibility demands of peer-reviewed research environments.

Safety, Handling & Laboratory Precautions

DSIP Nasal Spray is a research-grade chemical reagent and must be handled exclusively by trained laboratory professionals in accordance with applicable institutional biosafety protocols. Standard personal protective equipment (PPE) — including gloves, lab coat, and eye protection — should be worn during all handling procedures. This product is not approved for use in humans or animals, and must not be administered, ingested, or applied outside of a controlled research context. Researchers should consult the relevant Safety Data Sheet (SDS) and comply with all local, national, and international regulations governing the use of research peptides.

Reconstitution, Packaging & Storage

DSIP Nasal Spray is supplied as a pre-formulated aqueous solution in a metered-dose nasal spray bottle with a precision actuator. No reconstitution is required. Upon receipt, the product should be stored at 2–8°C in a refrigerator, protected from direct light and temperature fluctuations. Avoid freezing the solution, as freeze-thaw cycles may compromise peptide stability and spray actuator function. Always replace the cap securely after each laboratory use. Refer to the product label and CoA for lot-specific expiry information.

Intended Research Use & Market Positioning

DSIP Nasal Spray is intended exclusively for in-vitro research and laboratory investigation. It is of particular interest to researchers studying neuropeptide signaling pathways, hypothalamic-pituitary axis interactions, cortisol modulation, sleep architecture, and central nervous system receptor pharmacology. The intranasal delivery format makes it a practical research tool for studies examining peptide transport dynamics and mucosal absorption kinetics in experimental models. Direct Anti Peptide positions this product as a premium, competitively priced research reagent for sale to qualified scientific institutions, universities, and licensed research facilities worldwide.
