Parameter | DEPC | DEPC/ergosterol | DEPC/lanosterol | DEPC/cholesterol |
---|---|---|---|---|
γ0 in mN/m | 0.42 ± 0.03 | 0.71 ± 0.03 | 1.00 ± 0.05 | 2.45 ± 0.05 |
γ′ in nNs/m | <0.1 | <0.1 | <0.1 | 10.0 ± 0.2 |
Summary of the DLS results obtained at T = 22°C for pure DEPC membranes as a control and for three DEPC/sterol (6:4) mixtures, analyzed in terms of the Kramer theory (Eq. 1) giving the lateral tension γ0 and the surface viscosity γ′, where the latter parameter is—with the exception of cholesterol—below the detectable threshold value of γ′ = 0.1 nNs/m for our DLS setup.
