Paper Electrophoresis of Native Gastric Juice after Concentration by Dialysis against Carbowax 6000

Abstract

A method is presented for the concentration of native gastric juice by dialysis against a 30% solution of Carbowax 6000 in distilled water, prior to paper electrophoresis. Detailed descriptions of the dialysis procedure and subsequent vertical paper electrophoresis are given. The data show that the dialysis procedure is comparable to the lyophilization technic and has the advantage of faster processing, which makes the method applicable to routine clinical use in many diagnostic applications.
