 I don't have an answer to this question, but it reminded me of a
a similar question I've had for some time.  When I do in situs, I
use a riboprobe.  Is there any RNase that will digest double-stranded
RNA?  I've asked a lot of people, and no one ever heard of any.  The
significance of this is that I wouldn't need to bother with gloves
or DEPC-treated reagents after this point if I were sure it didn't
matter.
