Finally, after the DNA, RNA, or protein molecules have been separated using gel electrophoresis, bands representing molecules of different sizes can be detected.

Two-dimensional polyacrylamide gel electrophoresis (PAGE) is used for separation of complex protein mixtures by the independent parameters of isoelectric point and molecular weight. Isoelectric ...
