title: [A new method for the determination of the multiple molecular forms of gamma-glutamyltransferases after electrophoresis on cellulose acetate. Preliminary data].
abstract: What is described is a new, sensitive, simple and precise method for the visualization of the multiple molecular forms of the gamma-glutamyltransferase by means of electrophoresis on cellulose acetate in parallel with the serum protein pattern. The isoenzymatic pattern in 100 cases with a normal catalytic activity was mainly represented by two bands, one in the alpha 1 region and one in the alpha 2. Also examined was the serum of 103 cases having various hepatic biliary pathologies and a catalytic activity out of the reference interval, in an attempt to evaluate the diagnostic usefulness of the various isoenzyme patterns.
