Figure 2. Long gaps are present in the single-channel recordings for SUR and TMD0/Kir6.2Δ26 channels.
A, representative continuous recordings containing a single active channel measured for SUR1, S1-TMD0, SUR2A and S2-TMD0 co-expressed with Kir6.2Δ26. Downward deflections represent channel openings here and in all subsequent figures. Long gaps ranging from 1 to > 10 s are clearly present in these recordings. B, stability plot (see Methods) of a single-channel recording for SUR1/Kir6.2Δ26. The presence of a long gap is indicated by a much longer mean closed time (one peak in the closed time plot is out of scale) and results in a large drop in Po in the stability plot.
