Oxytocin: Research overview, identity, and laboratory handling guide

Cyclic disulfide nonapeptide studied in vitro for oxytocin receptor binding and peptide stability research. ≥99% HPLC. Research use only. This guide covers identity, published research context, procurement checks, and storage — RUO only, no clinical claims.

What Oxytocin is in published 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.

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.

Store sealed lyophilized vials at -20 °C protected from light. Reconstitute with compatible lab solvent, aliquot immediately, and avoid repeated freeze/thaw cycles.

CoA includes MS identity, HPLC purity, and net peptide content. Batch records are filed by lot.

The material class "Cyclic nonapeptide (research)" helps procurement teams group Oxytocin with related reference peptides during comparative studies.

Sequence and identity

Oxytocin identity on the catalog: Common name: Oxytocin; Sequence: Cyclo(Cys-Tyr-Ile-Gln-Asn-Cys)-Pro-Leu-Gly-NH2; Length: 9 residues; Molecular formula: C43H66N12O12S2; Molecular weight: 1,007.19 g/mol; Appearance: White lyophilized powder; Purity (HPLC): ≥ 99%; Net peptide: Listed on CoA; Solubility: Soluble in bacteriostatic water or dilute aqueous acid for stock preparation. Copy these into receiving and LIMS before reconstitution.

Mechanisms studied in published research

Mechanism-focused research on Oxytocin is typically conducted in cell lines or biochemical preparations that express the relevant receptor or binding protein for its class.

Design controls that include scrambled-sequence or orthogonal-receptor negative controls when your protocol evaluates Oxytocin pharmacology in vitro.

Report effect sizes with lot number and CoA reference so results can be reproduced if the same Oxytocin SKU is reordered later.

Avoid extrapolating in vitro binding or signaling readouts to whole-organism outcomes; RUO materials are not qualified for clinical investigation.

Procurement and identity verification

Request the lot-specific CoA for Oxytocin at receipt. Verify SKU, variant size if applicable, and identity mass before the lot enters general storage.

Compare HPLC purity to your internal minimum for the peptide family. File chromatogram excerpts when your QMS requires raw data.

Enter net peptide content from the CoA into inventory before calculating molarity for Oxytocin working stocks.

Attach purchase order, packing list, and CoA in one audit folder per lot.

Storage and reconstitution

Store lyophilized Oxytocin sealed at -20 °C protected from light unless the CoA states otherwise.

Reconstitute with bacteriostatic water or a buffer validated for your assay pH. Aliquot to limit freeze-thaw.

For oxidation-sensitive sequences in Oxytocin, minimize open-vial time at room temperature during weighing.

Comparative reference points

Researchers comparing Oxytocin with adjacent catalog references often evaluate the following SKUs in parallel plates:

Use matched reconstitution buffers and stock concentrations when running comparative binding or signaling assays.
