What Is Oxytocin?

Oxytocin is a cyclic nonapeptide hormone studied extensively as an agonist of the oxytocin receptor (OXTR), a class A GPCR, in neuroendocrinology and social-behavior research models.

Research Background

Oxytocin research examines OXTR-mediated calcium signaling and downstream gene-expression pathways in both peripheral (uterine, mammary) and central-nervous-system cell and animal models.

StorageStore lyophilized material at -20°C long-term or 2-8°C short-term, protected from light and moisture. For laboratory research use only.

Preparing a Laboratory Stock Solution

For in-vitro assay preparation, researchers calculate a target concentration (mg/mL) from the vial's labeled mass and the volume of sterile diluent added, then aliquot and store per standard laboratory cold-chain practice. This is a laboratory dilution calculation only, performed strictly for analytical or in-vitro research purposes. Not for use in humans or animals.

Storage & Handling

Lyophilized powder should be stored at -20°C for long-term stability, or refrigerated (2-8°C) for short-term use, protected from light and moisture. Once reconstituted for laboratory use, follow standard cold-chain handling and use within the timeframe indicated by your institution's protocols.

Third-Party Verification

Oxytocin ships with a QR-linked, batch-specific certificate of analysis (COA) confirming identity and purity via HPLC. Researchers should always confirm the lot number on their vial matches the COA on file before beginning any assay.

Sourcing & Quality

This reference material is manufactured and quality-tested to support reproducible research outcomes. Every batch is independently verified before it ships, and COAs remain accessible for future reference.
