IEF-based multidimensional applications in proteomics: Toward higher resolution

Abstract

This review focuses on the alternative isoelectrofocusing methods and IEF-related techniques in protein analysis and characterization. The main emphasis is placed on the evaluation of the resolving power of new approaches, as well as potential advantages of IEF-related techniques for multidimensional analysis. In particular, the inverse 2D gel electrophoresis where the Mw separation stage precedes IEF mode is considered. © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
