1. In an apparatus for gel electrophoresis in which a sample of fluorophore-labelled DNA fragments is caused to migrate by electrophoresis through a gel electrolyte layer in an electrophoresis plate in a first direction, thereby separating the sample into individual DNA fragments, and laser light is launched into a linear irradiation region of said gel electrolyte layer in a second direction which is generally perpendicular to said first direction with the emitted fluorescence being detected to determine the base sequence of the particular DNA, the improvement wherein a mirror for reflecting fluorescence is provided at the back of the electrophoresis plate in such a way that it is parallel to said linear irradiation region and the fluorescence reflected from said mirror is received by a separate fluorescence detector composed of a solid-state imaging device.
