ABSTRACT:
Electrophoresis systems and methods comprise an electrophoresis device, wherein the electrophoresis device comprises a loading channel, an injection channel, and a separation channel. The loading channel is in fluid communication with a first and second sample port. The injection channel is connected to the loading channel to form a first intersection. The separation channel is connected to the injection channel to form a second intersection and in fluid communication with a first and second reservoir, and wherein the injection channel is in fluid communication with a third reservoir. The electrophoresis system further comprises electrodes coupled to the first sample port and the third reservoir, and the first reservoir and the second reservoir, respectively, that are adapted to move the sample into the loading channel towards the third reservoir and form a sample plug in the second intersection, and to further move the sample plug into the separation channel towards the second reservoir.
