Electrophoresis of gamma-glutamyltranspeptidase on cellogel. The appearance of the alpha2-beta band in positive LP-X sera.
Fractionations of serum gamma-glutamyltranspeptidase (gamma-GT) and determinations of the "abnormal serum lipoprotein X" (LP-X) have been carried out in sera from patients with different hepatobiliary disorders. LP-X was used to demonstrate or exclude cholestasis. One gamma-GT fraction, alpha2-beta, may be of interest to distinguish between extrahepatic obstruction and intrahepatic cholestasis as was revealed by statistical analysis.
