A Combined Free-Flow Electrophoresis and DIGE Approach to Compare Proteins in Complex Biological Samples.

A Combined Free-Flow Electrophoresis and DIGE Approach to Compare Proteins in Complex Biological Samples. Methods Mol Biol. 2019;1855:403-415 Authors: Fung KYC, Cursaro C, Lewanowitsch T, Cosgrove L, Hoffmann P Abstract Free-flow electrophoresis has been applied in numerous studies as a protein separation technique due to its multiple advantages such as fast and efficient sample recovery, high resolving power, high reproducibility and wide applicability to protein classes. As a stand-alone platform, however, its utility in comparative proteomic analysis is limited as protein samples must be run sequentially rather than simultaneously which introduces inherent variability when attempting to perform quantitative analysis. Here we describe an approach combining fluorescent CyDye technology (DIGE) with free-flow electrophoresis to simultaneously separate and identify differentially expressed proteins in a model cell system.
