Abstract |
Gel-based proteomics has been widely used for the systematic cataloging of the protein constituents of defined biofluids, purified organelles, individual cell types, heterogeneous tissues and isolated organs, as well as being applied to comparative biochemical and biomedical analyses of complex biological specimens. Of the many electrophoretic techniques used in modern biochemical approaches, large-scale protein separation by difference gel electrophoresis (DIGE) has established itself as the most powerful analytical tool in comparative proteomics. Both 2-dye and 3-dye fluorescence systems with minimal or saturation labeling are routinely used. This chapter briefly describes the technical advantages of the pre-electrophoretic fluorescent labeling technique and discusses the bioanalytical usefulness of this highly successful electrophoretic method. |
