Hi Gary and Netters,

How about T-tailing the blunted vector and A-tailing the Pfu-generated insert with Taq Polymerase in 72 deg C for 30 min ?
They should ligate okay without all the troubles with CIP and PNK, I think.  Right ???

Hope this is useful info.   :-)

P.S.  I am merely a GradStudent.
One should take a HUGE grain of salt with whatever I have typed above.
Good Luck.   :-)
