agarose gels are precast bufferless gels with electrodes embedded in the agarose matrix.
Each gel contains an ion generating system, a pH balancing system, and DNA stain packaged
inside a transparent plastic cassette. Each gel cassette contains two ion exchange matrices (IEMs)
that are in contact with the gel and electrodes. The IEMs supply a continuous flow of ions
throughout the gel resulting in a sustained electric field required for running the gel.
