Classical two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) allows comparison and -quantitation of proteomes by visualization of protein patterns using gel stains and comparative image analysis. The introduction of fluorescent reagents for protein labeling (difference in-gel electrophoresis or DIGE) has brought substantial improvement in this field. It provides multiplexing of up to three samples in one gel, higher sensitivity compared to normal protein staining methods, and a higher linear range for quantitation. This article gives detailed protocols for 2D-DIGE, including both minimal as well as saturation labeling. © 2012 Springer Science+Business Media, LLC.
