Total-hCGβ Human Chorinonic Gonadotrophin Clinical Chemistry Reagent for In Vitro Diagnostic Reagents

Total beta human chorionic gonadotropintropin (hCG) is a kind of 237 amino acid glycoprotein secreted by the trophoblast cells  from the placenta, which is composed of α and β dimers  glycoproteins. Its main function is to stimulate the corpus luteum, which is conducive for the sustained secretion of estrogen and  progesterone, to promote the formation of deciduas and make  placental grow to maturity. After fertilization, hCG is secreted into  the maternal blood and will make rapid proliferation in the first  eight weeks of pregnancy. After that, it will decline slowly until the  first 18 to 20 weeks, and then remained stable.
