# Oxytocin – 10mg/vial (Research Use Only)

### Overview

Oxytocin is a 9-amino acid cyclic neuropeptide synthesized in the hypothalamus and released by the posterior pituitary, with one of the broadest published research profiles of any neuropeptide in mammalian biology. Originally characterized for its roles in uterine contractility and lactation physiology, oxytocin has emerged as a central subject of social neuroscience, wound repair biology, cardiac research, and gut-brain axis investigation. Its interactions with the oxytocin receptor (OXTR) — expressed in the brain, heart, gut, uterus, and immune cells — underpin a diverse and rapidly expanding research literature.

### What It Is

Oxytocin is a cyclic disulfide-bonded nonapeptide with the sequence Cys-Tyr-Ile-Gln-Asn-Cys-Pro-Leu-Gly-NH₂ (disulfide bond between Cys1 and Cys6). Molecular formula: C₄₃H₆₆N₁₂O₁₂S₂, MW ~1,007.19 Da. CAS number: 50-56-6. It acts as a GPCR ligand at the oxytocin receptor, activating phospholipase C and Ca²⁺ signaling cascades.

### Key Research Applications

- Oxytocin receptor (OXTR) binding, signaling, and downstream Ca²⁺ cascade research
- Social behavior, bonding, and prosocial neuroscience studies in rodent models
- HPA axis modulation and stress response attenuation mechanism research
- Wound repair, skin barrier function, and fibroblast activity studies
- Cardiac muscle contractility, myocardial protection, and cardioprotective mechanism research
- Gut motility, gastrointestinal innervation, and gut-brain axis research
- Anxiety, fear extinction, and limbic system modulation in behavioral pharmacology models
- Neuroendocrine axis cross-talk between oxytocin and vasopressin systems
