Oxytocin is a nine–amino-acid (nonapeptide) research material used to study GPCR signalling via the oxytocin receptor (OXTR), including Gq/PLC/IP₃/Ca²⁺ pathways, receptor selectivity, and peptide–receptor structure–activity relationships in controlled in-vitro systems.

Oxytocin — 2 mg

This cyclic nonapeptide contains a disulfide bridge between Cys₁ and Cys₆, with an amidated C-terminus. Consequently, it is widely employed to explore peptide receptor pharmacology, second-messenger responses, and cross-talk with vasopressin receptor families under non-clinical laboratory conditions.
For laboratory research only. Not for human use.

Handling & storage

Storage (dry): Keep vials at 2–8 °C, protected from light and moisture.
Reconstitution: Bring vial and diluent to room temperature. Reconstitute with
Bacteriostatic Water 10 ml. Swirl gently—do not vortex.
After reconstitution: Store at 2–8 °C, protect from light, use aliquots to reduce handling, and avoid repeated temperature cycling.
Compatibility: Use only within research protocols that follow your lab’s SOPs and local regulations.

About oxytocin in research

Researchers use oxytocin to probe OXTR signalling cascades (e.g., Gq/PLC/IP₃/Ca²⁺), receptor desensitisation and internalisation, and selectivity relative to vasopressin receptors in cell-based assays. These investigations focus on receptor pharmacology and downstream second-messenger dynamics exclusively in controlled, non-clinical in-vitro environments.

Synthesis & quality

Manufactured via controlled, validated peptide-synthesis processes to deliver high purity and lot-to-lot consistency. Each batch undergoes identity, purity, and appearance checks before release.
