Oxytocin (10mg) Research Peptide: A Nonapeptide for Neuroscience & Receptor Studies
If your research investigates neuropeptide signalling, social behaviour, or receptor pharmacology, Oxytocin (10mg) research peptide offers a precisely defined synthetic tool. Oxytocin is a nine‑amino‑acid cyclic peptide that acts as both a hormone and a neurotransmitter, playing a fundamental role in social bonding, reproductive physiology, and stress regulation. As the endogenous ligand for the oxytocin receptor (OXTR)—a class I G‑protein‑coupled receptor—it triggers intracellular calcium release and modulates gene expression in neurons and astrocytes.
Beyond its peripheral functions in uterine contractions and milk ejection, oxytocin has emerged as a key neuromodulator in the central nervous system, with implications for autism, anxiety, depression, and neurodegenerative disorders. This makes Oxytocin (10mg) research peptide a valuable tool for laboratories investigating neurochemistry, behavioural science, and receptor pharmacology.
At Wuhan Top Miracle Peptides, we supply high‑purity Oxytocin (10mg) research peptide to research institutions and wholesale buyers across the United Kingdom, France, Germany, Spain, Sweden, Italy, and the USA. Every batch is lyophilised, HPLC‑verified to ≥98% purity, and accompanied by a Certificate of Analysis (COA), ensuring your investigations into neuropeptide signalling, social behaviour, and receptor biology begin with uncompromising quality.
What Is Oxytocin and How Does It Work?
To fully appreciate the research potential of Oxytocin (10mg) research peptide, it is essential to understand its biochemical structure and the mechanisms by which it exerts its effects.
The Cyclic Nonapeptide
Oxytocin is a cyclic peptide consisting of nine amino acids: cysteine, tyrosine, isoleucine, glutamine, asparagine, cysteine, proline, leucine, and glycine, with a disulphide bridge between the two cysteine residues. Its sequence is Cys‑Tyr‑Ile‑Gln‑Asn‑Cys‑Pro‑Leu‑Gly‑NH₂, and its molecular formula is C₄₃H₆₆N₁₂O₁₂S₂. The peptide has a molecular weight of approximately 1007.2 Da and a CAS number of 50‑56‑6.
The peptide features a disulfide‑bridged hexacyclic ring (residues 1–6) and a linear tripeptide tail (residues 7–9). This cyclic structure is essential for its biological activity, as reduction and carboxymethylation of the disulfide bridge abolishes its function. The C‑terminal amide modification also contributes to its stability and receptor binding affinity.
Mechanism of Action: G‑Protein‑Coupled Receptor Signalling
The biological activity of Oxytocin (10mg) research peptide is mediated through its interaction with the oxytocin receptor (OXTR), a class I G‑protein‑coupled receptor:
-
Receptor Binding: Oxytocin binds with high affinity to OXTR on target cells, triggering a G‑protein‑coupled signal transduction cascade.
-
Calcium Signalling: Receptor activation increases intracellular calcium concentrations, either from intracellular stores via the phospholipase C (PLC) pathway or via calcium influx.
-
Cellular Effects: This signalling cascade modulates gene expression, intracellular signalling, and specific proteins in both neurons and astrocytes.
-
Neuromodulation: In the central nervous system, oxytocin regulates astrocytic gene expression and synaptic plasticity, influencing social behaviour, cognition, and emotion.
Research Relevance
Oxytocin’s diverse physiological roles—from peripheral reproductive functions to central neuromodulation—make it a versatile research tool. Studies have explored its neuroprotective and anti‑inflammatory properties, its ability to inhibit GSK‑3β and promote neuronal differentiation, and its potential to enhance neurogenesis and synaptic plasticity in models of age‑related cognitive decline. The peptide has also been investigated for its anxiolytic effects, with meta‑analyses supporting its role in modulating amygdala responses to emotional stimuli.

Reconstitution & Handling Protocol for Oxytocin (10mg)
Proper reconstitution of Oxytocin (10mg) research peptide is critical for maintaining its structural integrity and biological activity.
Step 1 – Preparation
-
Bring the sealed Oxytocin vial and your chosen diluent (sterile bacteriostatic water or sterile PBS, pH 5‑7) to room temperature. Condensation can degrade the lyophilised powder.
-
Clean your work surface with 70% ethanol and lay out sterile syringes, alcohol wipes and a clean work mat.
Step 2 – Vial Sanitisation
-
Wipe the rubber stopper of the Oxytocin vial with a fresh 70% ethanol wipe. Allow the alcohol to evaporate completely before piercing.
Step 3 – Reconstitution
-
Draw your desired volume of diluent into a sterile syringe. A common starting concentration for research applications is 10 mg per 1 mL of diluent, yielding a 10 mg/mL stock solution.
-
Insert the needle and slowly inject the diluent against the inner glass wall. Do not spray directly onto the lyophilised powder.
-
Gently swirl the vial until the solution is clear and fully dissolved. Do not shake vigorously, as shaking can cause denaturation.
Step 4 – Aliquoting & Storage
-
Immediately after dissolution, aliquot the reconstituted Oxytocin into single‑use sterile vials.
-
Store aliquots at –20°C. Avoid repeated freeze‑thaw cycles.
-
Once thawed, store at 2‑8°C and use within a short period.
