Electrophoresis medium membrane, pulse field electrophoresis method and apparatus.

摘要

A pulse field electrophoresis method comprises the use of an electrophoresis medium membrane comprising an aqueous agarose gel in which the thickness or concentration of said gel has a predetermined gradual change along the direction of electrophoresis. Or, a pulse field electrophoresis method comprises the steps of applying pulsed potential of different values to the anode side of an electrophoresis medium and to the cathode side of the electrophoresis medium, and making a duration time of each period of application of potential at the anode and a duration time of each period of application of potential at the cathode different from each other.
