Catechol-O-methyltransferase: A method for autoradiographic visualization of isozymes in Cellogel

Abstract
An electrophoretic procedure for separating the molecular forms of catechol-O-methyltransferase in cellulose acetate gel is described; the zones of enzyme activity were revealed by autoradiography. The electrophoretic patterns of the enzyme in several tissues and cell lines derived from four different species are presented.
