Two-dimensional difference gel electrophoresis (2D-DIGE) is an advanced variation of two-dimensional polyacrylamide gel electrophoresis (2D-PAGE); protein samples are labeled with different fluorescent dyes, mixed and separated by 2D-PAGE. 2D-DIGE solves major inherent drawbacks of 2D-PAGE, demonstrating great utility in biomarker studies. Biomarker development requires quantitative, reproducible, highly sensitive and high-throughput experimental platforms, and 2D-DIGE meets these criteria. Here we demonstrate the advantages of 2D-DIGE and discuss the possibilities 2D-DIGE offers for further, more comprehensive proteome studies.
