Extended Data Fig. 8: Multiple fluorescence intensity drops from single spots.

(a,b) Two example kymographs and accompanying intensity plots are shown. Top: Example kymographs of HT-PBP2B motion from smVerCINI videos showing several discrete drops in fluorescence intensity. Magenta segments: processive motion. Cyan segments: immobile. Bottom: Intensity traces for the tracks designated by dotted lines overlaid on kymographs.
