Product Overview

DSIP, or Delta Sleep-Inducing Peptide, is a well-characterized neuropeptide that has attracted significant scientific interest due to its involvement in sleep regulation, neuromodulation, and mitochondrial function. First isolated and identified in the 1970s, DSIP has since been the subject of numerous peer-reviewed studies examining its role in sleep architecture, somatostatin secretion, monoamine oxidase type A activity, and oxidative phosphorylation pathways. Researchers investigating neurological and endocrine mechanisms continue to find DSIP a compelling subject for controlled in vitro and preclinical study designs.

Peptide Structure & Amino Acid Sequence

DSIP is a nonapeptide composed of nine amino acid residues. Its primary sequence is: Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu. This short-chain neuropeptide has a molecular weight of approximately 848.86 g/mol and is recognized for its amphiphilic character, which contributes to its documented interactions with central nervous system receptors. The well-defined linear structure of DSIP makes it a reliable reference compound in neuropeptide research settings.

Purity & Analytical Verification (HPLC & MS)

Every DSIP Peptide Vial supplied by Direct Anti Peptide undergoes comprehensive analytical verification prior to release. High-performance liquid chromatography (HPLC) is used to confirm purity at ≥98%, while mass spectrometry (MS) validates the molecular identity and structural integrity of the peptide. These dual-method verification protocols ensure that researchers receive a product that meets the highest standards of analytical accuracy. Certificates of Analysis (CoA) are available upon request, providing full traceability for each production batch.

Quality Control & Lyophilization Integrity

The lyophilization process used in the manufacture of this DSIP vial is critical to preserving peptide potency, structural conformation, and long-term stability. Freeze-drying removes residual moisture under controlled vacuum conditions, producing a stable powder that resists degradation during storage and transit. Each vial is sealed under inert conditions to prevent oxidation, moisture ingress, and microbial contamination. The sterile glass vial format further protects the peptide from light exposure and environmental variables that could compromise research reproducibility.

Safety, Handling & Laboratory Precautions

This product is intended exclusively for use by trained research scientists and qualified laboratory personnel operating within appropriate institutional frameworks. Standard laboratory safety protocols must be observed at all times when handling this peptide. Appropriate personal protective equipment (PPE), including gloves, eye protection, and lab coats, should be worn. This compound must not be ingested, inhaled, or administered to humans or animals under any circumstances. All waste disposal must comply with applicable local, national, and institutional regulations governing research chemicals.

Reconstitution, Packaging & Storage

The DSIP Peptide Vial is supplied as a lyophilized powder in a hermetically sealed, sterile glass vial. Reconstitution should be performed under aseptic laboratory conditions using appropriate research-grade solvents as determined by the receiving institution’s protocols. Upon receipt, vials should be stored at -20°C in a dry, dark environment to maintain maximum stability. Once reconstituted, solutions should be aliquoted promptly and stored according to established laboratory best practices. Avoid repeated freeze-thaw cycles to preserve peptide integrity throughout the duration of the research project.
