Abstract
Disclosed herein is an on-line base sequencing apparatus, which is provided with electrophoresis tubes having a sheath flow part in each lower end thereof, which a sulfuric acid solution of pH 1.0 is continuously fed to form a sheath flow. The portions close to the outlets provided in the lower ends are irradiated with light which is close to 260 nm. In order to detect fluorescence components, each electrophoresis tube is provided with a detection system involving an interference filer for selecting that of 340 to 390 nm from the fluorescence components. Outputs of such four detection systems are successively identified, to determine base sequences.
