Crystal structure of human chorionic gonadotropin

Nature, 1994
The three-dimensional structure of human chorionic gonadotropin shows that each of its two different subunits has a similar topology, with three disulphide bonds forming a cystine knot. This same folding motif is found in some protein growth factors. The heterodimer is stabilized by a segment of the beta-subunit which wraps around the alpha-subunit and

Human Chorionic Gonadotropin

1976
Human chorionic gonadotropin (hCG) is a glycoprotein hormone that is synthesised by the syncytiotrophoblast cells of the placenta. The hormone is homologous in structure with human luteinising hormone (hLH) and shares with hLH similar qualitative biological actions on the ovary and the testis (Bishop, Nureddin and Ryan, 1976).

Radioimmunoassay for human chorionic gonadotropin

American Journal of Obstetrics and Gynecology, 1968
Abstract A radioimmunoassay method for HCG utilizing I 125 for iodination and a chemical procedure for separation of free and bound HCG 125 are described. This method is more sensitive and more accurate than the hemagglutination inhibition technique.

Determination of human chorionic gonadotropin

Best Practice & Research Clinical Endocrinology & Metabolism, 2013
Determination of human chorionic gonadotropin (hCG) is used for diagnosis and monitoring of pregnancy, pregnancy related disorders, for trophoblastic and some nontrophoblastic tumors. In addition, hCG is determined for doping control in males. Assay of hCG is complicated by the occurrence of different molecular forms, which are detected to various ...

Human chorionic gonadotropin in cancer

Clinical Biochemistry, 2004
Human chorionic gonadotropin (hCG) is mainly used for detection and monitoring of pregnancy and pregnancy-related disorders but it is also an extremely sensitive and specific marker for trophoblastic tumors of placental and germ cell origin. Thus treatment of relapsing choriocarcinomas and testicular germ cell tumors is often initiated on the basis of ...

Immunocytochemistry of human chorionic gonadotropin in human chorionic villi

American Journal of Obstetrics and Gynecology, 1987
The immunocytochemical localization of human chorionic gonadotropin was investigated in chorionic villi from the seventh to twelfth week of gestation. By the light microscopic peroxidase-antiperoxidase technique, positive reactions of human chorionic gonadotropin were found exclusively in the syncytiotrophoblast.
