Which is better: RPA or RT-PCR

[Marisol Rodriguez Pena]

Hi there!,
Firstable I have to tell you that I do not have practical experience in 
RPA BUT I spent quite a lot of time reading about it a couple of months 
ago when I had to check for the expression of a transgene in a 
transgenic mouse. I finally decided to go for the RT-PCR aproach and 
although I manage to get some specific bands relativelly fast, I had a 
lot of problems with the specificity and sensitivity of the assay. In 
any case, for me at that time both sample amount and weak expression 
were limiting factors.
If I were you, and as you have PCR running I will try a couple of times 
RT PCR (of course with the apropriate controls) with mRNA because it is 
really fast. If you decided to move to RPA, Ambion has a lot of 
information (no afiliation) about everything concerning RNA work, 
including a KIT for RPA (not very cheap BTW).

Hope it helps



Greatings
