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...
متن کاملChorionic 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...
متن کاملTSH-Lutropin/Chorionic Gonadotropin Receptors
We examined the relative effects of thyrotropin (TSH) and TSH receptor autoantibodies in the sera of patients with autoimmune thyroid disease on three TSH-lutropin/chorionic gonadotropin (LH/CG) receptor extracellular domain chimeras. Each chimera binds TSH with high affinity. Only the chimera with TSH receptor extracellular domains ABC (amino acids 1-260) had a functional (cAMP) response to th...
متن کاملImmunohistochemical Localization of Human Chorionic Gonadotropin
Through the use of immunohistochemical techniques, human chorionic gonadotropin has been localized to syncytiotrophoblastic cells of immature placenta, hydatidiform mole, chorioadenoma destruens, and choriocarcinoma. No gonadotropin has been detected in cytotrophoblast. Evidence is discussed which suggests that syncytiotrophoblast is the cell of origin of human chorionic gonadotropin. The obser...
متن کاملDiscordant results in human chorionic gonadotropin assays.
Discordance has been reported in human chorionic gonadotropin (hCG) concentrations measured by different immunoassay kits. We examined the results for 40 serum samples assayed with 10 different hCG immunoassay kits. Results varied considerably. Individual sample results varied by as much as 58-fold. Average results for different kits varied by as much as 1.4-fold for pregnancy (20 samples) and ...
