Mobility of RNAP2 Ser2ph foci compared with p300-enriched foci. RNAP2 Ser2ph-mintbody and Halo-p300 were expressed in HeLa cells, and fluorescence images were acquired, foci were tracked, and MSDs with SEM. were plotted, as in Fig. 9. Numbers of analyzed foci are 1,554 (RNAP2 Ser2ph) and 2,026 (p300) from 7 cells each for RNAP2 Ser2ph (111–344 foci/cell) and p300 (242–387 foci/cell). Scale bars, 5 µm; 1 µm for magnified views.
