The R10 pool undergoes structure-switching in an ATP concentration-dependent manner. (A) Gel images of PCR-amplified R10 DNA eluted by ATP concentrations ranging from 2–100 μM (lane 3-8). Lane 1 is 20 bp ladder, lane 2 is buffer only. (B) The half-maximal effective concentration (EC50) of the R10 SSA pool, calculated from the intensity of the sample bands, is 22.1 ± 3.5 μM at a 30 nM concentration of SSA pool/cargo strand (1:1.5 ratio).
