Figure 4

Laurdan excitation spectra of pure lipid bilayers at emission wavelength (λem = 435, 470 nm) in 20°C. The symbols indicate the type of lipid bilayer: DPPC (open triangle), DOPC (closed circle), PSM (open circle), and DHPSM (closed square). All spectra were normalized with the strongest peak intensity. The Laurdan excitation spectra of binary systems (DOPC/PSM, DOPC/DHPSM) are also shown in Fig. S6. The spectral differences are found in our experiments compared with previous report are considered to originate from the difference of purity of the lipids (between extracted SM and purified SM).
