Typical ESR spectra of 5-PCSL and 16-PCSL spin labels incorporated into the fluid phase of pure lipid bilayers of DPPC (a, c, black lines), DPPG (e, g, red lines) and DPPS (i, k, olive lines), and the mixtures of 0.1 mol% CTX relative to the lipid concentration of DPPC (b, d, black lines), DPPG (f, h, red lines) and DPPS (j, l, olive lines). The spectra were acquired at 60 °C, and its total width is 100 G. Blue lines correspond to the best fittings of the experimental spectra by the theoretical simulations (see MM).
