  • Pre-processing/electrophoresis integrated cartridge, pre-processing integrated capillary electrophoresis device, and pre-processing integrated capillary electrophoresis method
    Patent number: 9657286
    Abstract: To allow fully automated implementation of all steps of from pre-processing up to electrophoresis. Provided is a pre-processing/electrophoresis integrated cartridge including one or more block structures corresponding to the individual steps of pre-processing. Each block structure includes (1) a first block having a reaction tank, a reagent tank, a plurality of flow channels that connect the tanks, a plurality of control valves arranged in the flow channels, and a flow channel that connects a reaction tank in a block structure located at a preceding stage and a reaction tank in a block structure located at a next stage, and (2) a second block having a phoretic solution tank, a cathode buffer solution tank, a wash solution tank, a flow channel that connects a carrier tank in the block structure located at the preceding stage and the phoretic solution tank, and a control valve for the flow channel.
