Patent ID: 7282129

Claim:
A method for compacting a biomolecule band or patch having undergone electrophoresis in a gel electrophoretic system including (i) an electrophoretic cell with a gel medium, a band or patch of biomolecules in said gel, and an electrical grid, said grid having a plurality of closely spaced parallel electrodes extending between a first side of said grid and a second side of said grid, and (ii) a voltage controller adapted to provide a first multi-phase electrical signal at a first output in communication with said first side of said grid and a second multi-phase electrical signal at a second output in communication with said second side of said grid, said method comprising: electrophoretically separating a biomolecule sample to thereby produce a band or patch of biomolecules in said gel; generating said first multi-phase electrical signal at said first side of said grid; generating said second multi-phase electrical signal at said second side of said grid; thereby causing compaction of said band or patch of biomolecules in said gel.
