Base sequence detection apparatus and base sequence automatic analyzing apparatus

摘要

An analyzing apparatus characterized by comprising:
a detection unit which detects a target base sequence in a sample solution on the basis of a reaction between the target base sequence in the sample solution and a probe base sequence, including
a substrate (22) on which a channel (601) is formed, the sample solution, a reagent solution, or air being supplied to the channel (601),
a working electrode arranged in the channel (601) with the probe base sequence immobilized thereon,
a counter electrode (502) which is arranged in the channel (601),
a reference electrode (503) which is arranged in the channel (601), and
a sealing member (24a) which seals the channel (601) on the substrate; a supply unit (13) which supplies the reagent solution or air into the channel; a discharge unit (13) which discharges the sample solution, the reagent solution or air from the channel (601); a pump; a measurement unit (12) which applies a voltage between the working electrode and the counter electrode (502); a temperature control unit; a control unit which controls the supply unit (13b), discharge unit (13b), the measurement unit (12), and the temperature control unit; a memory unit which stores the electrochemical reaction signal as measurement data; and a processing unit which processes the measurement data to determine the target base sequence.
