hCG alpha Antibody

Human chorionic gonadotrophin (hCG) is a luteotrophic glycoprotein hormone secreted first by the trophoblastic cells of the fertilized ovum and later by placental tissue. The primary function of hCG is its luteotropic effect. Heterodimer of a common alpha chain and a unique beta chain confers biological specificity to thyrotropin, lutropin, follitropin and gonadotropin. hCG consists of non-covalently linked, alpha and beta subunits, 12 kDa and 24 kDa respectively, together constituting holo-hCG (MW 38 kDa). This antibody is specific for alpha-hCG.
