Fig. 3

a Salt resistance of coacervates formed from (Lys)10 and nucleotides (ADP and ATP). b Salt resistance of coacervates formed from (Arg)10 and nucleotides (AMP, ADP, and ATP). c Salt resistance of coacervates formed from Lys10-100 as length of (Asp)n increases (n = 5, 10, 30, and 100), and with Glu10. d Salt resistance of coacervates formed from (Arg)10 and (Asp)5,10 or (Glu)5,10. Critical salt concentrations determined from the fits for curves are available in Supplementary Table 1. Error bars show a–d standard deviation of measurements over at least three independent samples. Relative errors are minimally 10% turbidity values in panels a–d, and may not be visible on low turbidity values. See Supplementary Fig. 3 for individual trials of each experiment. e Measured (black circle) and calculated (green box) pH of the dilute phase, and calculated pH of coacervate droplets (red box) for different coacervate systems. See Supplementary Figs. 4 and 5 for calculations. Error bars show standard deviation of measurements over at least three independent samples.
