   We used Promega's RQ1 with considerable success (NAR16:4165 1988)
You will want to titer your enzyme to your prep; any useful data will
be derived from lots of runs and preps with lots of DNA will require
substantial DNase.  A non-rt/PCR control demonstrates you've used enough
to kill DNA signal.
