Immunological studies with a commercial preparation of human chorionic gonadotropin.

Effect of Adding Human Chorionic Gonadotropin to The Endometrial Preparation Protocol in Frozen Embryo Transfer Cycles

Fabrication of an Electrochemical Immunosensor for Determination of Human Chorionic Gonadotropin Based on PtNPs/Cysteamine/AgNPs as an Efficient Interface

An ultrasensitive electrochemical immunosensor for the detection of tumor marker human chorionic gonadotropin (hCG) was developed with a limit of detection as low as 2 pg mL-1 in phosphate buffer. The Platinum nanoparticles (PtNPs) were electrodeposited to modify the gold surface and to increase enlarging the electrochemically active sites, resulting in the facilitation of electron exchange. Cy...

P-234: Expression of Human Chorionic Gonadotropin (hCG) Hormone Using Chinese Hamster Ovary Cells

Background: Human chorionic gonadotropin (hCG) is a member of glycoprotein hormones family consist of two different non-covalently heterodimeric chains: alpha and beta subunits with 92 and 145 amino acids respectively. This hormone plays an important role in human reproduction and physiology especially for maintenance of the corpus luteum during the first months of pregnancy Materials and Metho...

The Higher Response of Vascular Endothelial Growth Factor and Angiotensin-II to Human Chorionic Gonadotropin in Women with Polycystic Ovary Syndrome

Background This research investigated the response of vascular active factors, vascular endothelial growth factor (VEGF) and angiotensin-II (AT-II) to ovarian stimulation during 24 hours in patients with polycystic ovary syndrome (PCOS). MaterialsAndMethods In this clinical trial study, 52 patients with PCOS and 8 control cases were stimulated with human chorionic gonadotropin (HCG) on the 4th ...

Immunoassay for Human Chorionic Gonadotropin Based on Glassy Carbon Electrode Modified with an Epitaxial Nanocomposite

      A highly sensitive electrochemicalimmunosensor was developed to detect hCG based on immobilization ofhCG-antibody (anti-hCG) onto robust nanocomposite containing Gr, Chit,1-methyl-3-octyl imidazolium tetra fluoro borate ionic liquid (IL)(Gr-IL-Chit). AuNPs were used to immobilize hCG antibody on the modifiedelectrode. The amine groups of the antibody are cova...
