Oxytocin

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

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