FIG. 7.

Polymer-salt coexistence phase diagrams of Ddx4^N1CS_pH7 at the l/l_B values indicated. The salt-free critical value of l/l_B is $l/{\left(l_B\right)}_{\mathrm{c}\mathrm{r}}=0.336$. Top gray circles in (a)–(c) provide the upper critical salt concentrations ${\left({\varphi }_s\right)}_{\mathrm{c}\mathrm{r}}^{\mathrm{U}}$, whereas the bottom gray circle in (c) provides the lower critical concentration ${\left({\varphi }_s\right)}_{\mathrm{c}\mathrm{r}}^{\mathrm{L}}$. Each dashed line in (a)–(c) is a tie line connecting a pair of coexistent phases. The three phase boundaries in (a)–(c) are compared in (d).
