I am not sure if I understand. Of course you can include EtBr in your gels
or buffer. I have never done it any other way. In fact after one run I
still use the same gel ( after cleaning it 5 volts overnight) but add about
20 ul of EtBr to the +end of the gel box. Upon running the DNA moving down
the gel will meet EtBr m,oving towards to the -Ve side.
