Figure 3
Fitted SAXS data (upper panel), SLD contrast profile (inset) and the absolute SLD profiles (lower panel) of (a) the two PC-based liposomes at 22°C, and of (b) the three PC/PS binary liposomes at 37°C. The data from the POPC/0.5% E liposome (own data, not published; incorporated E protein with a 200:1 lipid:protein molar ratio) and from the POPC/POPS (90/10) liposomes are shown in green and both are offset by 100. The SLD profiles from the two leaflets of the asymmetric bilayers are entered as different line types. The sketch of lipid molecules in the DPPC absolute SLD profile depicts the corresponding position of the headgroups, the tails and the interface between the two leaflets.
