Top : Molecular Biology : Electrophoresis : Agarose Gel Electrophoresis : Pulse Field Electrophoresis (PFGE)
Overview: Pulse Field Electrophoresis (PFGE) is based on the observation that during continuous field electrophoresis, DNA above 30-50 kb migrates with the same mobility regardless of size. If the DNA is forced to change direction during electrophoresis, different sized fragments begin to separate from each other. PFGE thus allows separation of larger pieces of DNA than conventional agarose gel electrophoresis.
