Fig. 6.
Dwell times in the absence (A,B) and presence (C,D) of 60 % PEG-400 at 1mM MgCl2 and 2mM ATP. (A,C) Changes in the intensity of scattered light from a single 75 × 35 nm nanorod attached to an F1-ATPase molecule during rotation for 45 ms acquired at 100 kHz for 0% and 60% PEG-400, respectively. Each data point is 10μs, and dwells are indicated by dotted lines. (B,D) Histograms of average F1 dwell times acquired at 100-200 kHz using the same nanorods and PEG-400 concentrations as in (A,C), respectively.
