Agreed. But for future reference, I like to digest with RQ1 DNAse for 15',
phenol extract and ppt. For even cleaner RNAs, I ppt. again with LiCl, although
a guy in my lab swears by 2 rounds of [RQ1 digestion and gel purification],
which gives him squeaky clean RNA, free of amplifiable template by PCR. This
is necessary for useful competitor RNAs for RT-PCR.
