BASE SEQUENCE DETECTING DEVICE AND BASE SEQUENCE AUTOMATIC ANALYZER

摘要

A base sequence detection apparatus includes a channel (601) which is formed on a base sequence detection chip (21) by a chip cartridge top cover (112) and sealing member (24a) along the flowing direction of a biochemical solution or air, a plurality of working electrodes (501) which are formed along the channel (601) and include a probe immobilized thereon, a plurality of counter electrodes (502) which are formed on the inner surface of the channel in correspondence with the working electrodes (501) and located on a plane parallel to the chip surface, a plurality of reference electrodes (503) which are formed on the inner surface of the channel (601) in correspondence with the working electrodes (501) and located on a plane parallel to the chip surface, an introduction port (116a) which introduces the biochemical solution or air from the upstream side of the channel (601) into the channel (601), a delivery port which delivers the biochemical solution or air in the channel from the downstream side of the channel, and a sample injection port (119) through which the sample is injected into the channel (601).
