Definition of Agarose gel

Agarose gel electrophoresis is the most commonly used technique for separating nucleic acid fragments that offers a broad separation range. A wide range of different sized nucleic acid molecules can be detected by adjusting the concentration of the agarose gel. The DNA/RNA samples may be separated by charge and/or size. The migration of nucleic acids in agarose gels is also affected by the choice of running buffer and the applied voltage.
