FAQ: Why do I see an extra band when I run the undigested heteroduplex on an agarose gel?
In some cases undigested heteroduplex DNA will run slightly slower than the homoduplex DNA. Depending on the composition of the mutations this can sometimes be seen as a band running above the homoduplex on an agarose gel.
