HCG is a glycoprotein hormone studied in gonadotropin receptor signalling research.\u003c\/p\u003e\n\u003cp\u003eHCG, human chorionic gonadotropin, is not a peptide in the sense most of this catalogue uses the word. It is a glycoprotein of roughly 36,700 molecular weight, built from two distinct subunits and carrying attached sugar chains.\u003c\/p\u003e\n\u003cp\u003eThat structure is why it is quantified in international units rather than milligrams. A glycoprotein’s sugar chains vary between preparations, so mass alone does not describe the material adequately, and a unit reflecting measured activity is the standard instead.\u003c\/p\u003e\n\u003cp\u003eIt shares its alpha subunit with several other gonadotropins, differing only in the beta subunit. That shared architecture makes subunit-level comparison a recurring theme in research using it, since specificity has to arise from the differing half.\u003c\/p\u003e\n\u003cp\u003eStudies using it concern receptor signalling and endocrine axis models in animal and cell-culture systems.\u003c\/p\u003e\n\u003ch2\u003eKey research areas\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGonadotropin receptor signalling research\u003c\/li\u003e\n\u003cli\u003eGlycoprotein subunit comparison studies\u003c\/li\u003e\n\u003cli\u003eActivity-based quantification methodology\u003c\/li\u003e\n\u003cli\u003eGlycosylation variation across preparations\u003c\/li\u003e\n\u003cli\u003eEndocrine axis models in animal research\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\u003eSize available:\u003c\/strong\u003e 5000iu\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 weight:\u003c\/strong\u003e ~36,700\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eRelated endocrine research material\u003c\/h2\u003e\n\u003cp\u003eOther sequences studied around endocrine signalling include \u003ca href=\"\/products\/kisspeptin\"\u003eKisspeptin\u003c\/a\u003e, \u003ca href=\"\/products\/oxytocin\"\u003eOxytocin\u003c\/a\u003e and \u003ca href=\"\/products\/sermorelin\"\u003eSermorelin\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003ch3\u003eWhy is HCG measured in international units?\u003c\/h3\u003e\n\u003cp\u003eBecause it is a glycoprotein whose sugar chains vary between preparations, so an activity-based unit describes it better than mass.\u003c\/p\u003e\n\u003ch3\u003eWhat is the vial size?\u003c\/h3\u003e\n\u003cp\u003e5000 iu, available singly, in a 3-vial pack, or in a 10 pack.\u003c\/p\u003e","brand":"Horizon Peptides","offers":[{"title":"5000 IU \/ 1 Vial","offer_id":50810705608929,"sku":"HP-HCG-5000IU-1","price":79.99,"currency_code":"CAD","in_stock":true},{"title":"5000 IU \/ 3 Vials","offer_id":50810705641697,"sku":"HP-HCG-5000IU-3","price":203.99,"currency_code":"CAD","in_stock":true},{"title":"5000 IU \/ 10 Vials","offer_id":50810705674465,"sku":"HP-HCG-5000IU-10","price":559.9,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0859\/2182\/4993\/files\/hp-hcg.webp?v=1791438962","url":"https:\/\/horizonpeptides.ca\/products\/hcg","provider":"Horizon Peptides","version":"1.0","type":"link"}
