Part of the Methods in Molecular Biology™ book series (MIMB, volume 276)


The recently developed whole-column-imaging detection technique for capillary electrophoresis (CE) and capillary isoelectric focusing (CIEF), a commercial whole-column-imaged CIEF instrument and its standard operation protocol are introduced. Furthermore, new developments and applications of whole-column-imaging detection in protein-protein interaction study, in protein separation using microfluidic devices and CIEF methods without carrier ampholytes, as well as in 2D separation techniques are reviewed. Miniaturization of whole-column-imaging CIEF and axially illuminated fluorescence whole-column-imaging CIEF are also discussed.
