Recombinase polymerase amplification is a single tube, isothermal alternative to the polymerase chain reaction. By adding a reverse transcriptase enzyme to an RPA reaction it can detect RNA as well as DNA, without the need for a separate step to produce cDNA. Because it is isothermal, RPA can use much simpler equipment than PCR, which requires a thermal cycler. Operating .
