An electrophoresis apparatus includes a sample separating section for containing a sample separating medium for separating a sample in a horizontal direction, the sample separating section containing the sample separating medium in such a manner that the sample separating medium has an exposed portion at least one end of a surface of the sample separating medium, the surface being in parallel with the horizontal direction; and medium connecting means for connecting a sample containing medium to the sample separating medium at a connecting region, the sample containing medium containing a sample, and the connecting region satisfying a particular equation. By this, an electrophoresis technique with better accuracy than conventional arts can be provided.
摘要:
A device for electrophoresis applies a voltage to a medium in contact with a plurality of electric conductors so that a potential of adjacent conductors is within a certain range. This allows preventing decline in electrophoresis speed. A device for electrophoresis and transfer includes an electrode having a plurality of electrode regions being insulated one another and arranged in a specific direction. This allows providing a practical and easy-to-use device for electrophoresis and transfer. A device for transfer alters an applied voltage or applied voltage duration to a certain position to another position. This allows improving transfer efficiency.
