There are good reasons why a gel purification is often better than
using column. I would nearly always include a gel purification step
in cloning, for various reasons, for example, if the vector used for
the PCR has the same restriction site (so a gel purification step
after PCR), or if the digested fragments you want to remvoe is too
big to be effectively removed by column. No problem with UV either,
as long as you use the right equipment, although the original poster
use crystal violet and don't need to use UV.
