Abstract: A plate on which a channel pattern is formed, which channel pattern includes a first channel into which a buffer agent is injected, and a second channel having, in a portion thereof, a quantification part that has a portion common to the first channel and holds a predetermined amount of a biological sample, the biological sample being injected into the channel including the quantification part, and the plate is rotated at a high speed by a filling unit to fill the buffer agent in the first channel, and thereafter, the second channel is pressurized by a discrimination unit to fill the biological sample in the second channel, and simultaneously, a predetermined amount of the biological sample is added into the buffer agent. Therefore, when performing discrimination of the biological sample, a discrimination result can be obtained accurately in a short time without the necessity of complicated preparation works.

Abstract: An electrophoresis apparatus having a plate on which channels are formed, a tray on which the plate is to be set, a tray driving unit for rotary driving the tray on which the plate is set, a voltage application unit for applying voltage to a buffer agent in the channels on the plate, an optical detection part for irradiating the channels on the plate with light, and detecting fluorescence that is generated from the sample due to the light irradiation. A plate clamp pressing the plate at only the channel formation areas of the plate against the plate setting surface of the tray, thereby fixing and holding the plate on the plate setting surface of the tray.

Abstract: An electrophoresis apparatus is provided with a plate 10 on which channels 110 are formed, a tray 22 on which the plate is to be set, a tray driving means 20 for rotary driving the tray 22 on which the plate is set, a voltage application means 30 for applying voltage to a buffer agent in the channels on the plate 10, an optical detection part for irradiating the channels on the plate with light, and detecting fluorescence that is generated from the sample due to the light irradiation, and a plate clamp 35 for pressing the plate 10 at only the channel formation areas of the plate 10 against the plate setting surface of the tray 22, there fixing and holding the plate 10 on the plate setting surface of the tray 22. Therefore, it is possible to prove a compact, light, and inexpensive electrophoresis apparatus which does not require complicated preparation works, and provides results accurately in short time.

Abstract: There is provided a plate (10) on which a channel pattern (110) is formed, which channel pattern includes a first channel (116) into which a buffer agent is injected, and a second channel (117) having, in a portion thereof, a quantification part (117a) that has a portion common to the first channel and holds a predetermined amount of a biological sample, the biological sample being injected into the channel including the quantification part, and the plate (10) is rotated at a high speed by a filling unit (20) to fill the buffer agent in the first channel, and thereafter, the second channel is pressurized by a discrimination unit (30) to fill the biological sample in the second channel, and simultaneously, a predetermined amount of the biological sample is added into the buffer agent. Therefore, when performing discrimination of the biological sample, a discrimination result can be obtained accurately in a short time without the necessity of complicated preparation works.
