  • Patent number: 5916428
    Abstract: An automated electrophoretic system is disclosed. The system employs a capillary cartridge having a plurality of capillary tubes. The cartridge has a first array of capillary ends projecting from one side of a plate. The first array of capillary ends are spaced apart in substantially the same manner as the wells of a microtitre tray of standard size. This allows one to simultaneously perform capillary electrophoresis on samples present in each of the wells of the tray. The capillary cartridge has two embodiments. In one embodiment, the second ends of the capillary tubes are also arranged is such an array. In a second embodiment, the second ends communicate with an interior cavity of pressure cell from which solutions, gels and the like may be introduced. The pressure cell allows for applying high pressure to clean out the capillary tubes. An apparatus for performing automated capillary gel electrophoresis using such a cartridge is also disclosed.
