EXPAR on toehold/biotin-template-2. (A) Real-time fluorescence curves of EXPAR on standard template, biotin-template-2, or toehold/biotin-template-2 in response to 6.02 × 109 copies (10 fmol) let-7a at 55°C. The biotin-template-2 is a standard template labeled with a biotin at the second base from its 5′ terminus. The toehold/biotin-template-2 is a standard template with a biotin at the second base from its 5′ terminus and a dumbbell-shaped hairpin at its 3′ terminus. (B) Real-time fluorescence curves of EXPAR on toehold/biotin-template-2 in response to different amounts of let-7a at 55°C. (C) Plots for the POI of EXPAR on toehold/biotin-template-2 versus logarithmic amount of let-7a.
