THE PREPARATION OF CHORIONIC GONADOTROPIN BY CHROMATOGRAPHIC ADSORPTION

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

Quantification of Human Chorionic Gonadotropin by Bovine Serum Albumin Nanoparticles

Background and Aims: Some nanoparticles can be used in immunoassays to increase sensitivity. This study aimed to evaluate a novel nano-immunoassay based on bovine serum albumin nanoparticles (BSA NPs). Materials and methods: At first, the nanostructure was synthesized, and then applied as a tag in the nano-immunoassay. Then the concentration of β-subunit of human chorionic gonadotropin ...

Immunological studies with a commercial preparation of human chorionic gonadotropin.

Immunological methods are being used to determine human chorionic gonadotropin (HCG) in urine and serum during pregnancy (1-4) and also to localize it in tissues and tumors (5). The antisera used in these studies (1-5) were produced by immunizing rabbits with HCG preparations of widely varying specific activities. The HCG-HCG antisera characterization studies that were performed primarily with ...

Human Chorionic Gonadotropin

A highly active preparation of human chorionic gonadotropin has been obtained by simple methods of column chromatography on diethylaminoethyl Sephadex and Sephadex G-100. The preparation appeared homogeneous by disc and immunoelectrophoresis, ultracentrifugation, and end group analysis. It assayed at 12,000 i.u. per mg by the rat prostrate gland and accessory sex organ method. The ~20,~ value w...

Chorionic Gonadotropin in Obesity

It is universally acknowledged that to be overweight is a serious handicap. The literature abounds with insurance statistics which show that the death rate is higher among the obese of every age group. No informed person would deny that obesity is a cause for concern or that it is a legitimate-even essential-subject for much further scientific and clinical investigation. The truth is that scien...
