THE PREPARATION OF AN APPARENTLY HOMOGENEOUS GONADOTROPIN FROM HUMAN MENOPAUSAL URINE*

Abstract
Extracts with gonad-stimulating activity, prepared from postmenopausal urine by the kaolin method, were purified on DEAE-cellulose columns. The resulting material was apparently a homogeneous glycoprotein, containing several N terminal amino-acids and possessing both follicle-stimulating and luteinizing activities.
