Research Profile

  • Nine-amino-acid cyclic neuropeptide
  • Oxytocin receptor (OXTR) agonist
  • Third-party purity tested
  • Research use only

Oxytocin is a nine-amino-acid cyclic neuropeptide characterised in the biochemical literature as an agonist at the oxytocin receptor (OXTR). Supplied as lyophilised powder for in-vitro research use only.

The above describes how this compound is characterised in the published peer-reviewed literature. It is not a claim about effects in humans.

Laboratory Handling

Oxytocin is supplied as a lyophilised (freeze-dried) powder in a sealed glass vial. For laboratory reconstitution, add the desired volume of diluent (typically bacteriostatic water) slowly down the side wall of the vial. Swirl gently until fully dissolved - do not vortex or shake. Store reconstituted solutions at 2–8 °C and use within 4–6 weeks.

Use our Reconstitution Volume Calculator to compute the resulting mg/ml concentration.
