Description

OVERVIEWProduct overview

Oxytocin is a nine-residue cyclic neuropeptide produced in the hypothalamus and released from the posterior pituitary.

It is among the most extensively studied neuropeptides in behavioural and physiological research.

All published work is preclinical or investigational. This material is supplied as a laboratory reference compound and is not authorised as a medicine in Ireland, the UK or the EU.

SUPPLY IN IRELANDOxytocin Ireland — supplied to research laboratories

Research groups across Ireland buy Oxytocin from Kensington Laboratories as a lyophilised Oxytocin peptide, released only against a batch-matched certificate of analysis. Every vial of high purity Oxytocin is verified by HPLC and LC-MS before it leaves the facility, so laboratories ordering Oxytocin in Ireland receive material with documented purity and identity.

Laboratory Oxytocin is packed for controlled storage and sent by tracked delivery in 3–5 days to Dublin, Cork, Galway, Limerick and the rest of Ireland. Delivery costs €9.90 per order. Teams planning Oxytocin research can review the specifications, certificate of analysis and reference list on this page before ordering.

Institutions searching for Oxytocin peptide suppliers in Ireland typically compare purity, batch documentation and delivery times. Each of those is published here: a 99% HPLC purity specification, a certificate matched to the batch code on your vial, and tracked delivery in 3–5 days.

Oxytocin is supplied strictly for laboratory research use only. It is not a medicine and is not for human or veterinary consumption.

RESEARCHResearch overview

The following summary is provided for educational and scientific context only. It describes what has been observed in published laboratory and animal studies and does not represent established clinical outcomes, medical advice or a claim of efficacy in humans.

Background

Oxytocin is a nine-residue cyclic neuropeptide produced in the hypothalamus and released from the posterior pituitary.

It is among the most extensively studied neuropeptides in behavioural and physiological research.

All published work is preclinical or investigational. This material is supplied as a laboratory reference compound and is not authorised as a medicine in Ireland, the UK or the EU.

Current research areas

Published investigation clusters around a small number of biological themes. Each remains experimental and none has been established as a therapeutic effect in humans.

  • Oxytocin receptor binding assays
  • Social behaviour models in rodents
  • Uterine and mammary smooth muscle preparations
  • Receptor cross-talk with vasopressin

Scientific context and proposed mechanisms

Signalling occurs through the Gq-coupled oxytocin receptor and phospholipase C, raising intracellular calcium in target tissue.

Interpreting the evidence

Most published work in this area uses cell culture or rodent models with small group sizes and short observation windows. Independent replication varies considerably between compounds, and results are sensitive to species, route, dose and endpoint.

There is no regulatory-approved human protocol for this compound. Any laboratory protocol should be defined by the model under study, institutional ethical approval, appropriate controls and predefined endpoints.

    FAQSFrequently asked questions
    What is Oxytocin?
    Oxytocin is endogenous cyclic nonapeptide, also referred to in the literature as OT, nonapeptide hormone. Laboratory interest centres on neuropeptide and smooth muscle signalling models. It is not a licensed medicine and is supplied for research use only.
    What quantity of Oxytocin is supplied?
    Each vial of Oxytocin contains 10 mg of lyophilised powder. Vials are individually sealed, with the batch number and expiry date printed on the label so stock can be matched to its published certificate of analysis.
    What purity is Oxytocin released at?
    Purity is the proportion of material that is the target peptide, with the remainder consisting of truncated sequences, salts and residual solvents from synthesis. It is measured by reverse-phase HPLC, and Oxytocin is released at 99% or higher.
    What does the certificate of analysis for Oxytocin show?
    The certificate reports the identity and purity of the exact batch you receive: the HPLC purity percentage, mass confirmation by LC-MS, the independent testing laboratory, the batch number and the test date. Every batch of Oxytocin is tested before release.
    Is Oxytocin suitable for human use?
    No. Oxytocin is supplied strictly for in-vitro and preclinical laboratory research by qualified professionals. It is not for human or veterinary consumption and is not licensed as a medicine.
    What is Oxytocin studied for in research models?
    Published work using Oxytocin concerns oxytocin receptor binding assays, social behaviour models in rodents, uterine and mammary smooth muscle preparations. All of this is preclinical, and none of it establishes a therapeutic use in humans.
    Is Oxytocin legal to buy in Ireland?
    Oxytocin may be supplied and purchased as a laboratory reference compound for research use only. It is not an authorised medicine in Ireland, the UK or the EU, and it must not be presented, sold or used as a treatment for any human or animal condition.
    How should Oxytocin be stored?
    Sealed lyophilised vials of Oxytocin are held at 2–8°C for short periods and at −20°C for long-term storage, protected from light. Once reconstituted, solutions are refrigerated and used within a short window; freeze–thaw cycling should be avoided.
    How much bacteriostatic water should be used with Oxytocin?
    There is no single correct volume — the amount of diluent used simply sets the concentration of the resulting solution. Many laboratories choose a round figure such as 2 ml per vial to keep calculations straightforward. Bacteriostatic water is not supplied and is purchased separately.
    How quickly is Oxytocin delivered in Ireland?
    Orders placed before the daily cut-off are dispatched with €9.90 tracked delivery in 3–5 days to Dublin, Cork, Galway, Limerick and addresses nationwide. Packaging is discreet and a tracking number is emailed on dispatch.
