Figure Lengend Snippet: (A) A representative image of real-time RT-RPA amplification products using the Twista fluorometer. The graph depicts the fluorescent signal for each template used in the RT-RPA reactions and the key to the left indicates the template each color represents. At approximately five minutes into run time a required Magnesium acetate (280 nM) adding step, to initiate the RPA reaction, was performed resulting in signal not being generated for the duration of that step (gap in the graph). (B) RPA amplification of Dengue 2 M gene. The numbers in the left margin indicate selected bands of the DNA marker, and the estimated amplified product size is indicated at 316 bp in the right margin. Lane 1 is a 50bp DNA ladder (Thermo Scientific™), lane 2 is the no-template control (water as template). Lanes 3 represent RPA amplification product from 10 copies of DENV-2 genome per reaction at 37°C.
