Research Background
Oxytocin is a nine-amino-acid cyclic neurohypophyseal peptide, stabilised by a disulfide bridge between two cysteine residues. It is supplied here as the acetate salt, the standard form for research-grade peptide handling, and is used in receptor-binding and neuroendocrine research on the oxytocin receptor family.
Proposed Mechanisms
Research Focus Areas
Oxytocin-receptor binding and signalling assays
Cyclic-disulfide peptide handling and stability studies
Neuropeptide-pathway model systems

FAQ
In what form is oxytocin supplied?
As the acetate salt, lyophilized, in 2 mg, 5 mg and 10 mg × 10-vial kits (price-list codes OT2, OT5, OT10).
What analytical documentation is provided?
A batch-specific COA with HPLC purity, MS identity and appearance data; the acetate content is stated where measured.
How should the lyophilized powder be stored?
Desiccated at 2–8°C, protected from light. After reconstitution, aliquot and freeze to avoid repeated freeze–thaw cycles and to limit disulfide-mediated aggregation.
Are human or veterinary applications implied?
No. This is a laboratory research reagent, FOR RESEARCH USE ONLY, with no dosing or administration information supplied.
All products are manufactured for laboratory research purposes only. Oxytocin Acetate is labeled FOR LABORATORY RESEARCH USE ONLY.
