Oxytocin in research
Oxytocin is a cyclic nonapeptide with an internal disulfide bridge. It is used as a sequence-defined reference in oxytocin receptor binding, peptide stability, and disulfide integrity research.
Disulfide identity verification
Lot-level identity data verifies the cyclic disulfide structure and C-terminal amide. HPLC purity and net peptide content are reported for controlled analytical and receptor assay preparation.
Storage and handling
Store sealed lyophilized vials at -20 °C protected from light. Reconstitute with compatible lab solvent, aliquot immediately, and avoid repeated freeze/thaw cycles.
Documentation
CoA includes MS identity, HPLC purity, and net peptide content. Batch records are filed by lot.

Storage and handling
Handle Oxytocin 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 Oxytocin 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 Oxytocin 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 Oxytocin?
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 Oxytocin?
Search by compound or lot number in the CoA Library: https://getblugen.com/coa-library/
What sequence is listed for Oxytocin?
The listed sequence is Cyclo(Cys-Tyr-Ile-Gln-Asn-Cys)-Pro-Leu-Gly-NH2. Confirm against the lot-specific CoA before release into inventory.
How should lyophilized Oxytocin 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 Oxytocin?
Yes. Academic labs and CROs can request quotes and NET-30 billing after vendor qualification via the contact/procurement desk.
