title: Synthesis of highly diversified carrier ampholytes. Evaluation of the resolving power of isoelectric focusing in the Pi system (alpha-1-antitrypsin genetic polymorphism).
abstract: The use of condensing reagents such as epoxypropanol, diepoxyoctane, acrylamide and N,N'-methylenebisacrylamide in the synthesis of carrier ampholytes increased the diversity of amphoteric components. The quality of these synthetic carrier ampholytes has been tested in the separation of variants of alpha-1-anti-trypsin, a genetic polymorphism called the Pi system. A resolving power of the order of 0.005 pH unit was obtained.
