(a) Dwell-time distributions in the dominant blockade levels for the pseudo-aptamer. The vertical dotted lines indicate the median dwell time for two levels. (b) Same analysis for the pseudo-aptamer bound to its corresponding 5 base pair sequence, with the emergence of third level not present in the unbound pseudo-aptamer. The two vertical dotted lines indicate the median dwell times for the first and second levels, while the third level median dwell time value extends to 9.54 ms (plot scale has been truncated for space).
