Figure 3.
Measured values of Tmix versus Δh at 22°C for bilayers of DiPhyPC/DPPC/Chol that fall (A) on a Tmix isotherm and (B) on a tie-line. Ternary phase diagrams at 22°C are from Veatch et al. (9), where shaded circles denote two liquid phases, open circles denote one liquid phase, and squares denote that a gel phase is present. Micrographs show that area fractions of the Ld phase increases from point b0 to b4. Dashed lines are not fits. Tables S2–S9 list values and uncertainties. (C) Phase boundary along the tie-line in (B). Solid points were determined in this study. The underlying shaded curve is not a fit. To see this figure in color, go online.
