Fig. 6: FRAP assay suggests liquid-like condensates.

FRAP recovery profiles for the condensate forming proteins. 6 out of 8 tested proteins show very fast dynamics (at a time scale of 20 s, indicated) indicative of liquid-like nature, while two (RBMY1D and TYW5) show no recovery at the indicated time. All the images with indicated whole nuclei (lower panel for each protein) are scaled to the 10 μm scale bar shown in the bottom right. FRAP experiments were repeated at least twice to ascertain the reproducibility of the results. Images are provided as Dataset S4.
