Figure 2

Lateral segregation of sphingosine (d18:1)-based ceramide analogs with saturated acyl chains of different lengths in POPC bilayers at 23°C. (A) Intensity-weighted average lifetime of tPA fluorescence in bilayers as a function of ceramide concentration. (B) Intensity-based longest-lifetime component of tPA fluorescence as a function of ceramide concentration. All ceramide analogs had sphingosine (d18:1) as a long-chain base. Each value is the average ± SEM; n = 2–3; ns, nanoseconds. To see this figure in color, go online.
