PURPOSE: To provide an electrophoretic apparatus analizing various samples simultaneously. CONSTITUTION: In a DNA base sequence determining apparatus having a plurality of electrophoretic channels wherein DNA fragments labelled with a fluorescent substance are migrated, a light irradiation means irradiating the electrophoretic channels with laser beam and a light detection means detecting the fluorescence emitted from the fluorescent substance by the irradiation with laser beam to detect DNA fragments, scanning means 2, 3, 4 scanning the laser beam of the light irradiation means to irradiate a plurality of the electrophoretic channels are provided. The light detection means 8 detects the fluorescence from the fluorescent substance labelling the DNA fragments migrated through a plurality of the electrophoretic channels in synchronous relation to the scanning of laser beam to discriminate the terminal base kinds of the DNA fragments migrating at every electrophoretic channels and determines the base sequence of a nucleic acid sample. Therefore, a migration lane interval can be reduced and the difference between the migration conditions between the migration lanes caused by temp. irregularity can be reduced. |
