Recombinant Antibody
Specificity
This antibody is specific for the core β subunit of the human chorionic gonadotropin hormone (hCG), a hormone produced by a part of the placenta, the syncytiotrophoblast, following implantation. The hormone has an important role during pregnancy, as it interacts with the LHCG receptor in the ovaries to prevent the degeneration of the corpus luteum, and thereby allows the secretion of progesterone during the first trimester. hCG is a heterodimeric glycoprotein, composed of an α and a β domain, of which the α is identical to that of LH and FSH, while the β is unique to hCG.
Alternative Names
hCG; CGA; Human chorionic gonadotropin; Choriogonadotropin subunit alpha; Chorionic gonadotropin chain alpha; CG-alpha

Application Notes
The binding reactivity of this antibody for human chorionic gonadotropin was determined using ELISA (PMID: 9930677). This antibody is specific for the β-subunit, and can be used in the detection of the hormone in pregnancy tests or in the diagnosis of uterine cancer.
