Abstract

In an electrophoresis device with numerous separation channels S loadable with samples, samples are loaded by applying samples in a shared injection channel I intersecting the separation channels S near a point where the injection channel I crosses one of the separation channels S. During exposure to a voltage in the injection channel, the samples are transferred to the separation channels S, and there electrophoretically separated.
