Here's a neat trick that works well for us particularly for
radiolabelling PCR products....
Take the gel on which you have just analysed your PCR product
and stick a sterile toothpick into the band you require ( -
useful if you have several fragments). Swirl the toothpick in
a tube containing your next round PCR components and place in
the PCR machine.
