Have you solved your inactivation DNase problem?
I have also a problem in inactivation of DNase. I inactive DNase by heating step 10min at 75°C. To check if the inactivation is efficient, I add 1ng DNA in my inactivated sample and I compare the results obtained in PCR with a control containing 1 ng DNA. There is a shift of 2 cycles with the inactivated sample. So I think that the Dnase is not totally inactivated and act on DNA added to destroy it. Have you got some solution to inactivate Dnase without damage RNA.
Thanks a lot.
rq : the Dnase that I used was the Turbo Dnase from ambion and I already test the inactivator of ambion's kit.
