2-D DIGE (2-D Fluorescent Difference Gel Electrophoresis) is a method of differential protein expression detection and quantitation at the protein level.  Up to three samples are labeled with one of three different fluorescent dyes, combined and separated on the same 2-D gel.  Like proteins migrate together, and the amount of a particular protein originating from each original sample is determined by scanning the gel at different wavelengths for fluorescent dye quantitation.  For additional information on 2-D DIGE go to:
