PURPOSE:To obtain an apparatus which is hardly affected by Joule heat and which can treat samples in large quantities by a method wherein a voltage is applied across the inner peripheral edge and the outer peripheral edge of a capillary disk which is provided with many capillary structures which are extended radially. CONSTITUTION:A required sample and a required reagent are poured into capillaries, capillary disks 6 which have been housed inside an electrophoretic tank 1 are then arranged in a state that they have been stacked between electrodes 3, 4, and the capillaries are immersed in an electrolyte buffer solution 2. In this state, a high voltage is applied across the electrodes 3, 4 by a high-voltage power-supply device 5, and an electrophoretic operation is started. A DNA synthesized substance in the sample is moved inside a gel, it is separated according to the magnitude or the like of its molecular weight, and a DNA band is produced. After the electrophoretic operation has been completed, every disk 6 is set in a fluorescence readout device, and the arrangement of bases in DNA is decided. Since the electrophoretic operation is treated by using many capillary structures which are installed on every disk 6 and which are extended radially, samples in large quantities can be treated, and the electrophoretic operation is hardly affected by Joule heat. |
