Are you purifiying the viral RNA in a lab where people work with cloned
copies of the gene? I've worked on PCRing viral genes for genotyping
and it's heartbreakingly easy to get contamination if you have to work
in a lab with cloned DNA floating around, even doing everything in a
Do you ever get contamination in the RNA- cDNA- control or only in the
RNA+ cDNA- control?
