Figure 4. Biphasic dissociation of HBsu.
Trajectories (log-scale in time) and kymographs showing dissociation of HBsu at indicated concentrations from the Cy3-labelled DNAs when washing with binding buffer without any protein. Each trajectory was corrected for photobleaching and averaged over 20–30 DNAs. Integrated intensity (top) and DNA length (bottom) were normalized by the maximum values. Time zero was defined as the starting point of protein dissociation and was shifted by 10 s for visualization. Scale bar, 10 s. Purple dotted lines indicate transitions from the fast to the slow dissociation phase for high protein concentrations.
