The peptide will be provided as lyophilized powder to ensure maximum stability.
Oxytocin is a nine-amino-acid peptide hormone. It is transported to the neurohypophysis via neural axons and released into the bloodstream under specific stimuli. In the reproductive system, oxytocin enhances smooth uterine muscle contractions, aiding childbirth and reducing postpartum bleeding risk. It also stimulates milk ejection by contracting mammary myoepithelial cells. In the nervous system, oxytocin acts as a neurotransmitter or modulator and regulates social behavior and emotions, promoting interpersonal trust, intimacy, and mother-infant bonding. Moreover, oxytocin shows potential regulatory effects on the cardiovascular system, gastrointestinal motility, and chronic pain. These broad physiological functions highlight its significant application values.

    Oxytocin 10mg — Cyclic Nonapeptide Hormone for Research

    Oxytocin (OT / OXT) is a cyclic nonapeptide hormone naturally synthesized in the hypothalamus and released from the posterior pituitary gland. Its structure consists of nine amino acids — Cys–Tyr–Ile–Gln–Asn–Cys–Pro–Leu–Gly–NH2 — with a characteristic disulfide bridge between the two cysteine residues (Cys1–Cys6) that forms the peptide's ring structure.

    Oxytocin is widely studied for its roles in reproductive physiology (uterine contraction and lactation) as well as its neuromodulatory effects on social behavior, bonding, and emotional regulation, making it a compound of broad interest in endocrinology and neuroscience research.

    Each vial contains 10mg of Oxytocin, supplied as a sterile white lyophilized (freeze-dried) powder to ensure maximum stability and long-term storage integrity.

    ▎Research Highlights

    • Reproductive Physiology Research: Oxytocin's classical roles include stimulation of uterine smooth muscle contraction and facilitation of milk ejection, making it a standard reference compound in reproductive endocrinology studies.
    • Neuromodulation & Social Behavior: Oxytocin acts as a neuromodulator in the central nervous system and is extensively investigated for its influence on social bonding, trust, maternal behavior, and emotional regulation.
    • Receptor Pharmacology: The oxytocin receptor (OTR) is a well-characterized G protein-coupled receptor; oxytocin serves as a key tool compound in receptor binding, signaling, and tracer development research.
    • Defined Cyclic Structure: The conserved Cys1–Cys6 disulfide ring shared with vasopressin makes oxytocin an important model peptide in structure–activity relationship studies.
    • Broad Research Applications: Investigated in studies spanning endocrinology, neuroscience, behavioral science, and reproductive medicine.

    ▎Mechanism of Action (Summary)

    Oxytocin exerts its effects primarily through binding to the oxytocin receptor (OTR), a G protein-coupled receptor:

    • Peripheral actions: activation of OTR on uterine smooth muscle and mammary myoepithelial cells, mediating contraction-related responses;
    • Central actions: neuromodulatory signaling in brain regions involved in social cognition, stress regulation, and emotional processing;
    • Receptor signaling: OTR activation couples to intracellular calcium mobilization and downstream second-messenger pathways in target tissues.

    ▎Storage & Handling

    Lyophilized Powder Store at 2–8°C, sealed and protected from light and moisture; for long-term storage, −20°C is recommended.
    Reconstitution Reconstitute with bacteriostatic water or sterile water; the peptide is readily soluble in aqueous solutions.
    After Reconstitution Store reconstituted solutions at 2–8°C and use promptly. Prepare aliquots to minimize repeated freeze-thaw cycles.
    Handling Notes Centrifuge briefly before opening to recover all contents. Handle with standard laboratory protective equipment.

    Quality Assurance

    Every batch of Oxytocin is verified by HPLC for purity and Mass Spectrometry for molecular weight confirmation. A Certificate of Analysis (COA) is provided with each order, and independent third-party testing reports are available upon request.
