Two-dimensional gel electrophoresis separates proteins according to their isoelectric points and molecular weight. Recent developments allowing improved resolution, detection and reproducibility, coupled with sensitive protein identification by mass spectrometry has made this methodology one of the most common tools for the study of proteomes in the postgenomic age.
