HCG — 5,000 IU
Product Description
Human Chorionic Gonadotropin, abbreviated as HCG or hCG, is a complex glycoprotein hormone composed of two non-covalently associated subunits known as alpha and beta. It is investigated in controlled laboratory models involving glycoprotein-hormone receptor binding, intracellular signaling and luteinizing-hormone receptor pathways.
Experimental investigations may examine interactions with the luteinizing hormone/choriogonadotropin receptor, commonly abbreviated as LHCGR, as well as receptor activation, cyclic-AMP-associated signaling and differences between urinary-derived and recombinant HCG preparations.
HCG is glycosylated and can exist in multiple glycoforms. Consequently, it should not be assigned one universal molecular formula or exact molecular weight. Recombinant choriogonadotropin alfa contains a 92-amino-acid alpha subunit and a 145-amino-acid beta subunit, with carbohydrate groups attached at multiple sites. DailyMed — Ovidrel
The 5,000 IU presentation describes biological activity rather than peptide mass. Source material, subunit identity, glycosylation profile, purity and potency should be confirmed using the batch-specific Certificate of Analysis. A 5,000-USP-unit vial is an established HCG presentation. DailyMed — Novarel
