  • High-pressure electrophoresis apparatus and method
    Patent number: 5938905
    Abstract: A high-pressure electrophoresis apparatus is formed by a high-pressure tubing (101) in which at least one column-shaped cell is arranged, said cell comprising two cell portions being arranged in the operating condition one above the other which form a cathode buffer solution reservoir (12) and an anode buffer solution reservoir (123) separated by a supporting member (122) which supports a carrier column loadable with a separating gel. Following implementation of high-pressure electrophoresis the carrier gel is extruded from the carrier column and subjected to further electrophoresis at normal pressure implemented on a slab gel.
