What is Oxytocin 5mg??
Oxytocin Acetate (CAS 6233-83-6) is the acetate salt of the endogenous nonapeptide neurohormone oxytocin. This 5mg/vial format is designed for research requiring larger quantities per assay — multi-concentration dose-response studies, high-throughput receptor binding assays, ex vivo uterine tissue preparations, or extended in vivo behavioural paradigms. Oxytocin acts at the oxytocin receptor (OTR, Gq/PLC/IP₃) to regulate uterine contractility, lactation, prosocial behaviour, anxiety, and pain modulation.
Research Applications
Dose-Response Studies
Multi-arm OTR activation across concentration ranges, receptor occupancy vs. effect profiling
Social & Anxiety Research
Higher-throughput social preference, social novelty, and elevated plus maze paradigms
Reproductive Biology
Uterine strip preparations, parturition timing, lactation in vitro assays
Pain Modulation
Spinal OTR analgesic pathways, hot-plate and formalin models at varied oxytocin concentrations
OTR Pharmacology
Desensitisation kinetics, internalisation, β-arrestin recruitment at elevated agonist exposure

Frequently Asked Questions
How do I reconstitute this peptide?
Add 1–2mL bacteriostatic water to the lyophilized vial by directing water down the inner wall of the vial. Swirl gently until the powder fully dissolves — do not shake or vortex. The solution should be clear and colourless. Use immediately or refrigerate at 2–8°C.
How should this peptide be stored?
Store lyophilized peptide vials at −20°C for long-term storage. Once reconstituted, store at 2–8°C (refrigerator) and use within 21–28 days. Avoid repeated freeze-thaw cycles, direct light, and heat exposure.
What purity is this QSC compound and how is it verified?
All QSC compounds are tested to ≥99% purity by HPLC peak area analysis on every production batch. Molecular identity is confirmed by mass spectrometry. A Certificate of Analysis (COA) is published on the product page and independently verifiable at verify.janoshik.com using the batch reference number.
