Fig 8. Phase separation of truncated FUS fragments of different lengths.

a) Phase diagram for each peptide. Dashed lines show the fitting to binodal of Flory-Huggins theory. b) The critical temperature. Dashed lines show the fitting using relation $T_c\propto N/{(\sqrt{N}+1)}^2$ with prefactor as the fitting parameter. c) The critical concentration. Dashed lines show the fitting using relation ${\rho }_c\propto 1/(\sqrt{N}+1)$ with prefactor as the fitting parameter. Temperatures are scaled by the critical temperature of [FUS40]₁. The corresponding slab density profiles are provided in S18 Fig.
