Fig. 7. Changing the directionality of movements on the phase diagram.
a Plot showing the change in salt concentrations in experiments that represent different compositions on the PDADMA/PAA phase diagram. HEPES and MgCl2 were added at 2.5 and 0.43 mM initially and increased in all samples with the same factor of increase of NaCl on the y-axis. b Partitioning coefficient, taken as [U15]coacervate phase/[U15]dilute phase, with different concentrations of salt for the same polymer concentrations. c Whole-droplet FRAP experiments of the same range of samples. The inset corresponds to a zoom-in on the low concentration samples. Supplementary Table 12 includes all the fitting parameters. Partitioning data are averages and standard deviations obtained from three trials. Means and standard deviations in FRAP are obtained from three samples with two bleached droplets per sample. Individual data points are shown as grey markers.
