What is Oxytocin and what receptor does it engage in research models?
Oxytocin is a nonapeptide neurohormone produced in the hypothalamus. It acts as an agonist at the oxytocin receptor (OTR) — a Gq-coupled GPCR expressed in the uterus, mammary gland, brain, heart, and immune tissue. In research, synthetic oxytocin is used as a reference agonist for OTR pharmacology, in reproductive cell signalling studies, and in neuroscience research on social behaviour-related signalling pathways.
What signalling pathways does OTR activation engage in research?
OTR is primarily Gq-coupled and activates phospholipase C, generating IP3 and DAG. IP3 releases intracellular calcium, producing the smooth muscle contraction responses characterised in uterine and myoepithelial research models. OTR also engages Gi in some cell contexts, reducing cAMP. In neuronal research models, OTR activation modulates dopamine, serotonin, and GABA neurotransmitter system interactions through intracellular signalling cross-talk mechanisms.
How is Oxytocin characterised analytically as a research compound?
Oxytocin is a cyclic nonapeptide with a disulfide bridge between Cys1 and Cys6. Identity confirmation requires mass spectrometry verifying a molecular weight of 1007.2 Da and confirmation of the disulfide-cyclised form versus the reduced linear form. LC-MS purity documentation and biological activity verification in a receptor-based functional assay (typically calcium mobilisation in OTR-expressing cells or in vitro uterine contraction assay) are standard quality requirements for research-grade oxytocin.
What research models use Oxytocin as a pharmacological tool?
OTR pharmacology research uses Gq biosensor assays and IP1 accumulation assays in OTR-expressing cells. Calcium imaging in primary hypothalamic neurons characterises oxytocin’s electrophysiological effects in neuronal models. Receptor selectivity profiling against the structurally similar vasopressin receptors (V1aR, V1bR, V2R) is essential for attributing effects specifically to OTR activation. Competitive binding assays using radiolabelled oxytocin characterise antagonist affinity at OTR.
Is Oxytocin from Elivena approved for clinical or obstetric use?
Oxytocin as supplied by Elivena is for research use in controlled laboratory settings only. It is not a research-grade product approved for clinical, obstetric, or human therapeutic administration. Research compounds are not manufactured to the sterility, pyrogenicity, or potency standards required for human injectable medicines.
What structural features make this nonapeptide unique for research?
Oxytocin contains a cyclic structure formed by a disulfide bridge between two cysteine residues, creating a six-amino-acid ring with a three-amino-acid tail. This structural feature makes it valuable for studying cyclic peptide chemistry, disulfide bond formation, and peptide stability. Researchers use this compound to investigate structure-activity relationships in cyclic peptides.
What are typical analytical research applications for this peptide hormone?
Research applications include peptide synthesis methodology development, analytical method validation for hormone detection, stability studies under various conditions, structure characterization techniques, and quality control method development. Specific applications depend on research objectives in peptide chemistry and analytical biochemistry. Research teams determine protocols based on their analytical investigation goals.
What are recommended storage conditions for this cyclic peptide?
Oxytocin can be stored at 2-8°C for short-term use or at -20°C for extended storage before reconstitution. After reconstitution, the peptide should be stored at 2-8°C and used according to institutional protocols. The cyclic structure and disulfide bridge require proper storage to maintain integrity. Researchers should establish stability protocols appropriate for their specific experimental requirements.
