Fluorescence 2-D difference gel electrophoresis (DIGE) uses spectrally resolvable dyes to label protein samples prior to 2-D electrophoresis. By using different fluorescent dyes to separately label protein samples multiple samples can be co-separated and visualized on a single 2-D gel. Differences between samples are resolved using image analysis software such as DeCyder 2D. This fluorescent multiplexing approach is compatible with mass spectrometry and overcomes many of the disadvantages of traditional 2-D analyses. A broad dynamic range provides more accurate quantitative data than traditional 2-D silver staining techniques while rapid image overlay simplifies image analysis and improves comparative accuracy.
