MJONES at CRC.AC.UK asked about RT-PCR:

Well, I am using the thermostable Perkin Elmer rTth polymerase (together with
their buffers) to amplify short regions from several RNA viruses.
I use a specific reverse primer of 25-27 nucleotides for the reverse
transcription step. So far I have not had any problems with this strategy but 
I have yet to  compare its efficiency directly with reverse transcriptase/TAQ 
Only problem on the horizon is the cost of the enzyme/kit :-(
I have yet to come across anyone else who has used this enzyme so I would be 
very interested in hearing others' experiences with this enzyme.
