It's a neat system where the ligase and the restriction enzyme are both 
present. The restriction enzyme cuts the vector and the unless the 
fragment of interest is inserted the restriction site is restored again 
and will be cut again. Once the correct fragment incorporates the restriction
site is lost. I am getting ready to use it myself.
P.S. Dan, Dr O'CONNEL's lab has used it successfully. It's supposed to be
really easy and effective.
