Fluorescence quenching by acrylamide of C34 (A) and C34-cholesterol (B) in the presence (filled symbols) and absence (empty circles) of lipid vesicles (5 µM peptide and 3 mM total lipid). Lipid compositions tested were pure POPC, POPC:Chol 2∶1 and pure DPPC. Dashed lines are fittings of the Stern-Volmer equation (eq. 3) to the experimental data.
