Oxytocin
Research-Grade Neuropeptide Hormone
Tagline: Social Behavior & Endocrine Research
Product Description
Oxytocin is a cyclic nonapeptide hormone synthesized in the hypothalamus and secreted by the posterior pituitary. It plays a critical role in social bonding, stress modulation, reproduction, and parturition.
Researchers use oxytocin in preclinical and in vitro models to explore its effects on maternal behavior, pair bonding, trust, lactation, uterine contractility, and the hypothalamic-pituitary-adrenal (HPA) axis. It is also studied for its role in neuropsychiatric and stress-related disorders.
For Laboratory and Scientific Research Use Only. Not for Human Consumption.
Why Researchers Choose Oxytocin
Highly Conserved Neuropeptide: Well-characterized structure and receptor system across species.
Social Neuroscience Tool: Widely used to study bonding, trust, and prosocial behavior.
Reproductive Research Applications: Critical in parturition and lactation physiology studies.
Stress & Anxiety Research: Modulates HPA axis and amygdala reactivity.
Batch Verified: ≥98% purity, HPLC-tested for consistency.

Research Applications
Social Bonding & Behavioral Neuroscience
Oxytocin administration has been shown to increase trust, pair bonding, and prosocial behavior in animal models and human studies [1].
Reproductive Endocrinology
Essential for uterine contractions during labor and milk ejection during lactation, making it a key hormone in parturition studies [2].
Stress & Anxiety Regulation
Research shows oxytocin modulates the HPA axis, reducing cortisol levels and dampening stress responses [3].
Neuropsychiatric Disorder Models
Explored as a modulator in studies of autism spectrum disorder, PTSD, and social anxiety [4].

Mechanism of Action (How Oxytocin Works)
OXTR Receptor Activation: Binds to oxytocin receptors (OXTR), a GPCR, triggering phospholipase C and IP₃-mediated Ca²⁺ release [Fuchs 1991].
Uterine Smooth Muscle Contraction: Increases intracellular calcium, promoting myometrial contraction [Fuchs 1991].
Central Nervous System Effects: Modulates amygdala and hypothalamic circuits involved in social behavior and emotion [Kosfeld 2005].
HPA Axis Suppression: Decreases CRH and ACTH release, lowering stress-induced cortisol secretion [Neumann 2008].
Neuroplasticity Support: Enhances synaptic plasticity and social memory formation [Guastella 2010].
