FIGURE 5

Semilogarithmic plots of the frequency of occurrence of PEG occupancy events versus PEG concentration. The values were corrected for missed events. The fits shown represent linear relationships between frequency of occurrence and PEG concentration. (A) Frequency of occurrence of the short occupancy events for five of the PEGs; (B) frequency of occurrence of the long spike events for five of the PEGs. ▪, PEG-0.94 k; •, PEG-2.0 k; ▴, PEG-3.1 k; ▾, PEG-4.2 k; ♦, PEG-6.0 k. Because τon−1 = τT/f1, τon−2 = τT/f2, and f1 + f2 = 1, the plots in A and B are related; e.g., τon−2 = τon−1(1/f1–1).
