HCG peptide is produced by the chorionic tissue of the placenta and plays a critical role in maintaining the corpus luteum and stimulating steroid secretion during early gestation. This Glycoprotein hormone is widely studied in reproductive endocrinology for ovulation induction, superovulation protocols, and fertility research.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails class=\"peptide-details\"\u003e\n\u003csummary\u003eMechanism of Action\u003c\/summary\u003e\n\u003cdiv class=\"peptide-content\"\u003e\n\u003cp\u003ehCG exerts its effects by binding to and activating the luteinizing hormone\/choriogonadotropin receptor (LH\/CGR), a G protein-coupled receptor expressed primarily in the ovary and testis. As a full agonist of the LH receptor, hCG mimics the actions of endogenous luteinizing hormone (LH). Upon receptor binding, it activates the adenylate cyclase signaling pathway, increasing intracellular cAMP levels, which in turn stimulates steroidogenesis—the production of progesterone and testosterone. Unlike LH, hCG has a longer half-life and exhibits biased agonism at the LH\/CG receptor, making it a valuable tool for studying gonadotropin receptor signaling.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails class=\"peptide-details\"\u003e\n\u003csummary\u003eResearch Applications\u003c\/summary\u003e\n\u003cdiv class=\"peptide-content\"\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReproductive Endocrinology:\u003c\/strong\u003e Investigated for ovulation induction, oocyte maturation, and corpus luteum support in fertility research.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperovulation Studies:\u003c\/strong\u003e Employed in preclinical models to induce superovulation in laboratory animals, including mice and rats, in combination with PMSG or eCG.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTestosterone Research:\u003c\/strong\u003e Used to stimulate endogenous testosterone production and study Leydig cell function.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSignal Transduction:\u003c\/strong\u003e Utilized as a ligand to probe LH receptor structure, function, and G protein-coupled receptor signaling pathways.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails class=\"peptide-details\"\u003e\n\u003csummary\u003eProduct Specifications\u003c\/summary\u003e\n\u003cdiv class=\"peptide-content\"\u003e\n\u003cp\u003e\u003cstrong\u003eCAS Number:\u003c\/strong\u003e 9002-61-3\u003cbr\u003e\u003cstrong\u003eMolecular Weight:\u003c\/strong\u003e ~37.9 kDa (glycoprotein, ~31% carbohydrate by weight)\u003cbr\u003e\u003cstrong\u003eStructure:\u003c\/strong\u003e Heterodimer of α subunit (92 aa, ~14.9 kDa) and β subunit (145 aa, ~23 kDa)\u003cbr\u003e\u003cstrong\u003ePurity:\u003c\/strong\u003e ≥ 98% (batch-dependent; refer to Certificate of Analysis)\u003cbr\u003e\u003cstrong\u003eForm:\u003c\/strong\u003e Lyophilized powder\u003cbr\u003e\u003cstrong\u003eStorage:\u003c\/strong\u003e Store at ≤ -20°C in a cool, dry place, protected from light and moisture\u003cbr\u003e\u003cstrong\u003eSolubility:\u003c\/strong\u003e Soluble in water; also soluble in aqueous glycerol and glycols; insoluble in ethanol\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"yuansensetech","offers":[{"title":"G5K","offer_id":52038356042018,"sku":"G5K","price":116.0,"currency_code":"USD","in_stock":true},{"title":"G10K","offer_id":52038356074786,"sku":"G10K","price":225.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1008\/2805\/3794\/files\/hcg.jpg?v=1783741731","url":"https:\/\/yuansensepeptide.com\/products\/hcg","provider":"Yuansensetech™","version":"1.0","type":"link"}
