Research brief · Hormone
Oxytocin
Cyclic nonapeptide hormone for OXTR neuroscience and reproductive research.
Class
Cyclic nonapeptide hormone
Half-life
~3–5 min
Studied in
Social behaviour, parturition and lactation research models.
What it is
Oxytocin is a cyclic nonapeptide hormone synthesized in the hypothalamus, signalling via OXTR. Research spans social-behaviour neuroscience and reproductive physiology.
Mechanism studied
Agonist at the oxytocin receptor (OXTR); CNS and peripheral signaling.
Research notes
- Very short plasma half-life shapes acute-exposure research designs.
Before sourcing any material
- Confirm a lot-matched third-party certificate of analysis (HPLC purity and mass-spectrometry identity).
- Check the stated peptide content per vial, not just the gross vial mass.
- Plan reconstitution volumes first so the vial size matches your protocol.
- Verify what is lawful in your jurisdiction — these are in-vitro research reagents, not medicines.
