Extended Data Fig. 9: Fluorescence intensity jumps.

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