Immunoreactive beta-core-like material in normal postmenopausal urine: human chorionic gonadotrophin or LH origin? Evidence for the existence of LH core.


Material with the immunochemical properties of the beta-core of human chorionic gonadotrophin (hCG) can be found in the urine of normal postmenopausal women. However, we have been unable to detect intact hCG (using an assay which is specific for the alpha-beta heterodimer of intact hCG) in serum of such subjects. The levels of serum LH and urinary beta-core… (More)
