Patent ID: 7854827

Claim:
A device providing an arrangement for separation of a complex protein sample based on multidimensional gel electrophoresis without the use of valves, the separation involving a first separation of the sample on the basis of isoelectric points and a second separation of the sample on the basis of molecular size, said device comprising: at least two first gel strips which provide for the first separation in a first dimension of the device; a single carrier supporting said first gel strips such that at least two analytical processes each involving the first separation and the second separation can be executed in parallel on said single carrier; and at least one opposite disposable surface provided in a first position from said single carrier, wherein when in said first position the surface is in contact with said first gel strips and moveable to a second position which provides a gap between said first gel strips and said surface such that a gel contacts each of said first gel strips and provides for the second separation in a second dimension of the device, and wherein at least two analytical processes each involving the first separation and the second separation can be executed in parallel.
