Figure 3

Stacked spectra showing the phase behaviour of two-lipid systems as a function of lipid head group composition. (A), DOPG/TOCL mixtures at 273 K; (B), DOPE/DOPG at 273 K; (C), DOPE/DOPG at 310 K; (D), DOPE/TOCL scan at 273 K. The 36:64 and 18:82 mixtures of DOPE:DOPG represent the ratio of these two lipids in the B period and at the C/D boundary, respectively. DOPG, dioleoylphosphatidylglycerol; TOCL, tetraoleoylcardiolipin; DOPE, phosphatidylethanolamine. Full temperature scans of each lipid mixture can be found in Figs S8–10.
