ABSTRACT:
A method and apparatus for zone electrophoresis which is completely automatic and which requires no manual handling of the electrophoretic medium or the serum sample to be tested. In a preferred embodiment, prefabricated (empty) electrophoresis tubes are placed into a turntable. An automatic diluter then loads, in one operation, known amounts of sample serum and the electrophoretic medium into the tubes. Electrophoretic separation is then achieved automatically by application of a suitable voltage. The electrophoretic pattern produced in the tube is then measured by an optical probe which is dipped into the tube without disturbing the electrophoretic pattern established therein. This probe moves through the electrophoretic medium and measures the pattern quantitatively. This measurement can be directly transmitted to utilization equipment, such as data processing apparatus.
