WebJan 1, 2024 · Reverse transcription RPA (RT-RPA) is designed to detect target RNA by incorporating cDNA synthesis and amplification at the same temperature in one tube. RT-RPA can be achieved by a nfo probe, bearing an internal base analog [e.g., tetrahydrofuran (THF)] located between a fluorophore (e.g., FITC) and a quencher with a blocked 3′ end. WebJul 21, 2024 · The real-time detection incorporates a fluorogenic probe besides forward and reverse primers, and the reaction initiates based on the cleavage of probe at an abasic site [i.e., tetrahydrofuran (THF) or a dSpacer (a derivative of the THF) or a dR group (the deoxyribose of the abasic site via a C-O-C linker)] between the fluorophor and the ...
