RPA Basic Primer Screening and Optimization. Target HPV gBlock DNA and no-target human genomic DNA were first amplified in RPA, and the resultant amplicons were diluted and analyzed in qPCR using the same primer pair as for the RPA reaction. The relative amplification yield of positive reactions, containing 50 or 100 input copies of target HPV DNA, to no-target reactions is displayed for primer pairs specific to (a) HPV16, (b) HPV18 and (c) HPV45. Data represent the mean relative amplification yield for nine replicates (three RPA replicates x three technical replicates). Outlined boxes indicate primer pairs with the greatest relative amplification yield for both 50 and 100 input copies of target HPV DNA that were chosen for tailed primer design.
