The wires connecting the cell to the power supply must be in good condition, not worn or cracked, and the banana plugs and jacks must be in good condition, not corroded or worn. Broken or worn wires can cause rapid changes in resistance, slow electrophoresis or a halt in the run. All cables and connectors must be inspected regularly for breaks and wear. The banana plugs on the ends of the wires should be removed from the power supply at the end of the run by pulling them straight out. Grasp the plug, not the wire. If pulled at an angle, the solder joint attaching the banana plugs to the wires can loosen and cause the loss of the electrical circuit. On the cell core, electrode banana posts with flattened baskets do not make good contact with the banana jack in the cell lid, and should be replaced. The banana jacks (female part) in the cell lid should be inspected regularly to make sure there is no corrosion. Before starting an electrophoresis run, dry any liquid on the horizontal surfaces of the cell, especially near the banana plugs and jacks. Any liquid on the horizontal surfaces of the cell can arc during the run, damaging the cell and stopping the electrophoresis.
