Gel Electrophoresis - Boston University

2008-9-9  Electrophoresis is the migration of charged particles ormolecules in an electric field. This occurs when thesubstances are in aqueous solution. The speed ofmigration is dependent on the applied electric fieldstrength and the charges of the molecules. Thus,differently charged molecules will form individualzones while they migrate. In order to keep diffusionof the zones to a minimum, electrophoresis
