STUDIES ON THE THYROTROPIC AND GONADOTROPIC SUBSTANCES BY “PAPERGRAPHY”

Abstract

By means of paper electrophoresis, the purified thyrotropic and gonadotropic substances were obtained. Some chemical and physiochemical characteristics of these substances have been established and comparative studies were made. Both substances were found in the γ-globulin fraction of ratserum. Contrary to gonadotropic substance, thyrotropic substance was unstable in the acid medium. The biologically active fractions of both substances contained galactose.
