Pulsed Field Gel Electrophoresis (PFGE)

The Method of Pulsed Field Gel Electrophoresis (PFGE)

Pulsed Field Gel Electrophoresis (PFGE) is a technique used for the separation of large deoxyribonucleic acid (DNA) molecules by applying to a gel matrix an electric field that periodically changes direction. As DNA larger than 15-20kb migrating through a gel essentially moves together in a size-independent manner, the standard gel electrophoresis technique was unable to separate very large molecules of …
