title: Two-dimensional gel electrophoresis; better than a poke in the ICAT?
abstract: To date, the most widely used technology for conducting proteomic studies has been two-dimensional gel electrophoresis (2DGE), but this approach does have drawbacks. Isotope-coded affinity tagging (ICAT) is starting to challenge 2DGE as a new proteomic tool for the analysis of proteins in complex biological specimens. An appraisal of these two methodologies reveals that neither ICAT nor 2DGE provide comprehensive coverage on a proteome-wide scale.
