Isoelectrofocusing in acetate membrane: the method and application.

Acetate membrane as a new medium for isoelectrofocusing was used in this study. The acetate membrane was specially produced for isoelectrofocusing, and contains a surface active agent. The ampholine solution system and isoelectric condition for this purpose are described. Polymorphic traits as alpha1-antitrypsin in human serum and 6-phosphogluconate dehydrogenase (6-PGD) in human erythrocyte could be identified by this method. The isoelectric patterns and the isoelectric points of these proteins were demonstrated on the acetate membrane.
