Sterile filtered white lyophilized (freeze-dried) powder. The Oxytocin was lyophilized from a concentrated (1 mg/ml) solution with no additives.


It is recommended to reconstitute the lyophilized Oxytocin in sterile 18MΩ-cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.


At ambient temperature.  Upon receipt, store at the temperature recommended below.


Lyophilized Oxytocin, although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution, Oxytocin should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
