TROUBLESHOOTING GUIDE Sample not moving or moving slowly on gel. Leads may be reversed. Check leads to power supply and gel box. Check upper buffer level is above the top of the short glass plate. Check the lower buffer level. If the level of the buffer is above the orange gasket, remove 20-50 mls of buffer until the level is below the gasket. Erratic voltage, voltage and/or current leak. (At the beginning of the run voltage is greater than 400V or readings are unstable.) Make sure that the electrical leads are not arcing due to condensation on the lid of the tank. Dry the area around the electrical posts on the inner box. Check that the leads to the power supply are connected securely. Verify that the power supply is operating properly. Band distortion in gel From time to time band distortions may occur when running O-linked gels, for various reasons, including: • Sample may be overloaded, use a maximum of 1/5 th of the volume of the labeling reaction for each lane. • Wells may have been torn when comb was removed. Remove comb slowly using a gentle back and forth rocking motion and lift vertically. • “Smile effect” on the gel may be the result of a gel not being cooled uniformly. Check that the cooling system is on and working properly, and is free of air bubbles in the electrophoresis box. Make sure that a stirring bar has been placed in the electrophoresis box and that the lower buffer is being mixed. Check that power supply is set for proper current level - see Section 4-III-11 for proper settings. • “Fuzzy bands” may be due to too high current used. Check Section 4-III-11 for proper settings.

Upper buffer chamber leaks when cassettes are in place. Check that the plates are clean, not cracked or chipped, and that they are centered on the inner core assembly. Once the wedge has been brought into position against the glass, gently push down to engage the sealing gasket. Check that the gaskets are not cracked and that they are seated properly in place (do not grease gaskets). Pushing down with slightly greater pressure can stop most minor leaks.
