Comparison of amplification factor between Whole Transcriptome Amplification (WTA) and Random Amplification (RA) protocols. The number of RVFV copies after amplification is expressed as a function of the amount of input DNA (in number of genome copies). Amounts of RVFV RNA before and after amplification were estimated by qPCR of RVFV as described in M&M.
