Table 2:
Membrane thickness measured from bilayer patches (see Fig. 5) and force curves (see Fig. 2) at different Chol/POPC mixing ratios. The values are shown as mean ± SD.
Chol/POPC mixing ratio | 0 | 1 | 1.5 | 2.5 | 3 | |
---|---|---|---|---|---|---|
Membrane height (nm) | Bilayer patches | 6.24±0.13 | 6.64±0.19 | 6.71±0.23 | 7.68±0.44 | 8.81±0.25 |
aForce curves | 5.78±0.14 | 5.87±0.15 | 7.62±0.20 | 8.35±0.18 | 10.58±0.35 | |
Water layer thickness (nm) | 2.34±0.35 | 2.07±0.32 | 2.14±0.35 | 3.11±0.51 | 4.24±0.36 |
Force curves are obtained for complete supported bilayer, and the membrane height includes water layer thickness.
