Fig. 3. Differences in emergent properties of polyR and polyK droplets.
a Confocal fluorescence images of FRAP recovery for polyK10/pU10-A488 (upper) and polyR10/pU10-A488 (lower) illustrating increased fluidity of polyK vs polyR. b FRAP recovery within droplets of polyK/pU10-A488 (green) and polyR/pU10-A488 (purple). c MSD vs lag time for polyK and poly R of length 10 (blue, o), 50 (red, o) and 100 (yellow, o) with UTP) illustrating increased viscosity of polyR compared to polyK. Inset: Brownian motion of 200 nm bead in polyK50/UTP (green) and polyR50/ UTP (purple).
