You are absolutely right as to the utility of thermostable enzymes for
working with RNA; and that there currently aren't any available. We (Life
Technologies/ GIBCO BRL) are trying to engineer a thermostable reverse
transcriptase. So far, we're still trying. If you'd like, I'd be glad
to put you in contact with the project leader.
Have a great 1996.
