DNA Polyacrylamide Gel Electrophoresis – UC Davis

Polyacrylamide gels are poured and run in 0.5x or 1x TBE at low voltage (1-8 V/cm) to prevent denaturation of small fragments of DNA by heating. Other electrophoresis buffers such as 1x TAE can be used, but they are not as good as TBE. The gel must be run more slowly in 1x TAE, which does not provide as much buffering capacity as TBE.
