Neuroendocrine Peptide
DSIP (Delta Sleep-Inducing Peptide) is a nonapeptide referenced in in-vitro neuroendocrine and pituitary hormone research. 10mg lyophilized powder.
What is DSIP (Delta Sleep-Inducing Peptide)?
DSIP (Delta Sleep-Inducing Peptide) is a nonapeptide referenced in in-vitro neuroendocrine and pituitary hormone research. 10mg lyophilized powder. Independently tested for purity and identity. For in-vitro laboratory research use only. Not for human consumption.
DSIP (delta sleep-inducing peptide) is a nonapeptide (Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) first isolated from rabbit cerebral venous blood. Each vial from Genetic Peptides USA is manufactured for in-vitro and laboratory research and is shipped from within the USA.
DSIP is studied in neuroscience models of sleep architecture, stress-hormone signaling, and neuromodulation in animal research. The information on this page summarizes published scientific context for educational purposes and is not a claim of any therapeutic effect.
Every batch of DSIP is independently third-party tested using HPLC (high-performance liquid chromatography) for purity and mass spectrometry (MS) for identity confirmation. Where a Certificate of Analysis is available for the current lot, it is displayed on this page. Researchers should verify the lot number on the vial against the COA for their records.
DSIP is supplied as a lyophilized (freeze-dried) powder, the most stable form for shipping and storage. Store unopened vials cool, dry and away from light; refrigeration at 2–8°C or freezing at -20°C is standard laboratory practice for long-term storage. Once reconstituted with a suitable solvent such as bacteriostatic water, keep refrigerated and follow your institution's handling protocols.
DSIP is a short, hydrophilic nonapeptide that dissolves readily in aqueous diluents. Because short peptides in solution are sensitive to enzymatic degradation and repeated freeze-thaw cycles, many laboratories split a reconstituted vial into single-use aliquots and freeze them. Record the lot number and reconstitution date for each aliquot so results can be traced to the matching Certificate of Analysis.
Where can I buy DSIP in the USA? Genetic Peptides USA ships DSIP research vials from within the United States with tracking on every order.
Is DSIP third-party tested? Yes. Batches are tested by an independent laboratory using HPLC/MS for purity and identity.
What form is DSIP supplied in? A lyophilized powder in a sealed vial, intended for reconstitution in a laboratory setting only.
Research Use Only: DSIP is sold strictly for laboratory research use only. It is not for human or animal consumption, not a drug, food, or cosmetic, and is not intended to diagnose, treat, cure, or prevent any disease. Purchaser assumes responsibility for proper handling in accordance with applicable laws.
