Cloning in pGEM-T

In my experience with pGEM-T, PCR product purification is not necessary if
you have a nice clean, specific PCR reaction (one major band on the gel).
If you clone direct from the reaction mix, you sometimes get one or two
contaminant inserts, but these occur at much lower frequency than the main
product and of course are easily distinguished on digestion
