Abstract: A new fluorescence detection method called pyrophosphorolysis activated fluorescence was developed to measure PAP amplification of nucleic acid. A fluorophore-quencher dual-attached blocked primer was used for PAP which has a fluorophore attached to a nucleotide in the internal region or at the 5? end and a quencher attached to a blocked nucleotide at the 3? end. Multiple fluorophore-quencher dual-labeled blocked primers were also used for multiplex PAP, which are attached with different fluorophores to distinguish multiple templates in a reaction.
