  • Running agarose and polyacrylamide gels

    2013-11-4 · Polyacrylamide gels are poured and run in 0.5x or 1x TBE at low voltage (1-8V/cm) to prevent denaturation of small fragments of DNA by heating. Otherelectrophoresis buffers such as 1x TAE can be used, but they are not as good asTBE. The gel must be run more slowly in 1x TAE, which does not provide asmuch buffering capacity as TBE. For electrophoresis runs greater than 8 hours,we recommend that 1x TBE buffer be used to ensure that adequate bufferingcapacity is available throughout the run.
