Bring the melted agarose to 60°C. The gel point is the temperature at which an aqueous agarose solution forms a gel as it cools. Agarose gel electrophoresis remains the most widely used technique for separating nucleic acid fragments because it is a simple technique that is nontoxic and offers a broad separation range. Voltage applied at the ends of an agarose gel generates an electric field with a strength defined by the length of the gel and the potential. Marker dye for loading DNA samples into gel electrophoresis wells and tracking migration during electrophoresis. Pulsed field gel electrophoresis DNA fragments longer than about 20kb cannot be resolved in conventional agarose gel electrophoresis because long DNA molecules align themselves as rods and migrate with a mobility that is independentof their length.
