IN fact, if you want to run a PFGE, which you run for much longer times
than conventional gels (in my particular case up to 10 days, although
2-5 days more common), you have to make sure the tank is completely
level, and the gel has to be poured also perfectly level... otherwise
the dna will not run evenly or on a straight line...
