Phase separating coacervate structure and energy shows no significant sequence effect. a Polycation/polyanion pair correlation function for the coacervate phase at various τ (boxed points in Fig. 2a). Correlations do not show strong dependence on τ. b Calculation of the change in electrostatic energy for the polycation (from g(r) such as in a) show small, positive increases in energy during coacervation. This is qualitatively consistent with experimental data in Fig. 3
