I have heard that borate can cause DNA damage so that some people stay away
from borate containing buffers when the want to use the DNA for further
cloning.  However, I have been using TBE recently with the GeneClean II
system and have had no problems.  For me its easier to use TBE because our
lab makes it up in 20L carboys.  Also, I believe TBE gives better
resolution so I've stopped using TAE altogether.
