DSIP in research
DSIP is a 9-residue neuropeptide reference sequence used in laboratory work around peptide stability, chromatographic behavior, and neuropeptide assay development.
Analytical reference value
The compact sequence makes DSIP useful for HPLC method development and MS confirmation workflows. CoA documentation provides identity, purity, and net peptide content.
Storage and handling
Store lyophilized material sealed at -20 °C away from light. Reconstitute in compatible lab solvent, aliquot into working volumes, and avoid repeated freeze/thaw.
Documentation
Each lot includes CoA data and batch records filed against the SKU.

DSIP research overview
DSIP is a research-use-only material for qualified laboratory programs. This page summarizes identity fields, storage and handling, CoA review, and linked research resources for procurement and QA.
Catalog class: Neuropeptide reference (research).
Key identity fields
- Common name
- Delta sleep-inducing peptide / DSIP
- Sequence
- Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu
- Length
- 9 residues
- Molecular formula
- C35H48N10O15
- Molecular weight

Storage and handling
Handle DSIP as a lyophilized research reagent: cold, dry, light-protected storage; choose reconstitution buffer per your SOP; plan aliquots to limit freeze–thaw; and keep the lot CoA with the inventory record.
Research framing
Use DSIP in published model-system terms only — receptor family, pathway context, assay controls, and concentration planning. Do not transfer assumptions from adjacent peptides without a documented comparison protocol. Research use only.
Documentation checklist
- Storage and stability records for the received lot
- Lot CoA with HPLC, MS identity, and net peptide content
- Literature and assay context filed with the protocol
- Verify lots in the CoA Library
Product FAQ
Is DSIP intended for human or clinical use?
No. BluGen listings are research use only (RUO) for qualified laboratory programs — not clinical, diagnostic, therapeutic, veterinary, food, drug, or cosmetic use.
What documentation ships with DSIP?
Each lot includes a certificate of analysis with HPLC purity, MS identity confirmation, and net peptide content. Verify lots in the CoA Library.
Where can I verify the current-lot CoA for DSIP?
Search by compound or lot number in the CoA Library: https://getblugen.com/coa-library/
What sequence is listed for DSIP?
The listed sequence is Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu. Confirm against the lot-specific CoA before release into inventory.
How should lyophilized DSIP be stored?
Store sealed vials cold, dry, and protected from light per the lot CoA and your institutional SOP. Aliquot reconstituted stock to limit freeze-thaw cycles.
Can institutions request a quote for DSIP?
Yes. Academic labs and CROs can request quotes and NET-30 billing after vendor qualification via the contact/procurement desk.
