Oxytocin is a nine-residue neuropeptide studied in receptor signalling research.\u003c\/p\u003e\n\u003cp\u003eOxytocin is a nonapeptide, Cys-Tyr-Ile-Gln-Asn-Cys-Pro-Leu-Gly-NH2, with a molecular weight of 1007.19. Its two cysteine residues form a disulfide bridge, closing the first six residues into a ring with a three-residue tail extending from it.\u003c\/p\u003e\n\u003cp\u003eIt holds a particular place in peptide chemistry history: it was the first polypeptide hormone to be chemically synthesised, work that established much of the methodology the field still relies on. That heritage is why it appears so often as a benchmark compound in method development.\u003c\/p\u003e\n\u003cp\u003eIt differs from vasopressin, a closely related nonapeptide, at only two positions. The pair are a standard teaching example of how minimal sequence differences produce distinct receptor selectivity, and they remain a common control pairing in binding studies.\u003c\/p\u003e\n\u003cp\u003eResearch using it concerns receptor binding and neuropeptide signalling in cell-culture and animal models.\u003c\/p\u003e\n\u003ch2\u003eKey research areas\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eOxytocin receptor binding and selectivity assays\u003c\/li\u003e\n\u003cli\u003eDisulfide-bridged cyclic peptide research\u003c\/li\u003e\n\u003cli\u003eSynthesis methodology benchmarking\u003c\/li\u003e\n\u003cli\u003eComparative studies against vasopressin\u003c\/li\u003e\n\u003cli\u003eNeuropeptide signalling models in cell culture\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFormat:\u003c\/strong\u003e lyophilized powder in a sealed research vial\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSizes available:\u003c\/strong\u003e 5mg and 2mg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack options:\u003c\/strong\u003e 1 vial, 3 vials, or 10 pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMolecular formula:\u003c\/strong\u003e C43H66N12O12S2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMolecular weight:\u003c\/strong\u003e 1007.19\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSequence:\u003c\/strong\u003e Cys-Tyr-Ile-Gln-Asn-Cys-Pro-Leu-Gly-NH2\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eRelated neuroendocrine peptides\u003c\/h2\u003e\n\u003cp\u003eOther endocrine-signalling sequences stocked here include \u003ca href=\"\/products\/kisspeptin\"\u003eKisspeptin\u003c\/a\u003e, \u003ca href=\"\/products\/hcg\"\u003eHCG\u003c\/a\u003e and \u003ca href=\"\/products\/vip\"\u003eVIP\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003ch3\u003eHow is the ring formed?\u003c\/h3\u003e\n\u003cp\u003eA disulfide bridge between the two cysteine residues closes the first six into a ring.\u003c\/p\u003e\n\u003ch3\u003eWhat vial sizes are stocked?\u003c\/h3\u003e\n\u003cp\u003eTwo: 2 mg and 5 mg.\u003c\/p\u003e","brand":"Horizon Peptides","offers":[{"title":"2mg \/ 1 Vial","offer_id":50810705150177,"sku":"HP-OXYTOCIN-2MG-1","price":49.99,"currency_code":"CAD","in_stock":true},{"title":"2mg \/ 3 Vials","offer_id":50810705182945,"sku":"HP-OXYTOCIN-2MG-3","price":124.99,"currency_code":"CAD","in_stock":true},{"title":"2mg \/ 10 Vials","offer_id":50810705215713,"sku":"HP-OXYTOCIN-2MG-10","price":349.9,"currency_code":"CAD","in_stock":true},{"title":"5mg \/ 1 Vial","offer_id":50810705248481,"sku":"HP-OXYTOCIN-5MG-1","price":82.99,"currency_code":"CAD","in_stock":true},{"title":"5mg \/ 3 Vials","offer_id":50810705281249,"sku":"HP-OXYTOCIN-5MG-3","price":211.99,"currency_code":"CAD","in_stock":true},{"title":"5mg \/ 10 Vials","offer_id":50810705314017,"sku":"HP-OXYTOCIN-5MG-10","price":580.9,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0859\/2182\/4993\/files\/hp-oxytocin.webp?v=1791438984","url":"https:\/\/horizonpeptides.ca\/products\/oxytocin","provider":"Horizon Peptides","version":"1.0","type":"link"}
