Extended Data Fig. 1: Electrophoretic analysis of the strand displacement reaction using TEprobes with different reverse toeholds.

a, Schematic illustration of the strand displacement reaction using TEprobes with different reverse toeholds. b, Sequences of TEprobes. c, Electrophoretic images of the products of the strand displacement reaction. Concentrations of TEprobe and the target RNA were both 500 nM. The strand displacement reaction was proceeded for 20 min. The strand displacement reaction was hindered by increasing the reverse toehold length up to 9 nt.
