Oxytocin Overview
Oxytocin is a cyclic nonapeptide with a disulfide bridge between cysteine residues at positions 1 and 6, synthesized as a prohormone in hypothalamic magnocellular neurons and transported to the posterior pituitary for release. Through binding to its target receptor (OXTR), a G-protein-coupled receptor, it activates phospholipase C-mediated pathways leading to intracellular calcium release and protein kinase C activation. Research models examine oxytocin’s effects on smooth muscle signaling dynamics, myoepithelial contraction modeling, CNS behavioral pathways, stress response signaling, and autonomic nervous system modulation in laboratory settings.

History
Oxytocin was first isolated from the posterior pituitary gland by Henry Dale in 1906, who observed its smooth muscle signaling properties. The complete amino acid sequence was determined by Vincent du Vigneaud in 1953, and he successfully synthesized the peptide shortly thereafter, earning the Nobel Prize in Chemistry in 1955. This represented the first synthesis of a polypeptide hormone and established oxytocin as a foundational molecule in peptide biochemistry and neuroendocrinology.

We do not sell syringes and do not provide guidance regarding mixing, dosing, administration, or research protocols.
This product is intended exclusively for in vitro laboratory research and testing. It is not intended for human or animal use, consumption, administration, or application under any circumstances. Use and handling are restricted to qualified or licensed professionals in appropriate laboratory settings.
This product has not been approved by the FDA and is not a drug, food, cosmetic, dietary supplement, or medical product. It may not be marketed, represented, labeled, or used as such.
Shipping Disclaimer
All USAPEP orders are shipped with UPS and include insurance coverage for packages that are lost, stolen, or damaged while in transit. Orders totaling more than $200 are eligible for complimentary 2–3 day shipping.
Once a shipment is accepted by UPS, delivery timing is managed by the carrier and cannot be guaranteed by USAPEP Research. While most orders are delivered within 2–5 business days, transit delays may occur due to weather, holidays, weekend processing pauses, increased carrier volume, or other conditions beyond our control.
Our research materials are packaged in protective boxes to help safeguard vials from sunlight exposure and temperature changes during transit. Because lyophilized, or freeze-dried, research peptides are formulated for stability and can withstand elevated temperatures for extended periods, cold packs are not used in our shipments.
Product Care & Storage
- Store at -20°C (freezer) for long-term stability.
- Keep away from light, moisture, and heat.
- Once reconstituted, store at 2–8°C (refrigerator).
- Discard any solution that becomes discolored or shows signs of contamination.
