A procedure in which proteins or DNA are separated on a gel for
their detection, characterization, or quantification. Sodium dodecyl sulfate
- polyacrylamide gel electrophoresis (SDS-PAGE) is used for protein, while agarose
gel electrophoresis is used for DNA. Electrophoresis separates the components
of the sample into discrete zones separated by their size (or alternatively,
by charge), with each zone containing one or more proteins or DNA. Sometimes,
gel electrophoresis is followed by a western blot anaysis. (Western
Blot)
