ABSTRACT:
A device providing an arrangement for the separation of a sample mixture for analytical reasons based on multidimensional gel electrophoresis and method thereof are disclosed. The separation involves a first separation in a first dimension of the device on the basis of isoelectric points and a second separation in a second dimension of the device on the basis of molecular size. At least two gel strips for the first dimension separation step and a corresponding gel for the second dimension separation step are provided. The two gel strips are arranged on a single carrier either on the same side or on opposite sides. By having at least two gel strips arranged in such a manner at least two analytical processes can be executed in parallel on the single carrier without the use of valves.
