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
