Schematic of the experimental setup. Membrane complexes were prepared with DMPC and DMPS lipids, cholesterol and amyloid-${\mathsf{\beta }}_{22-40}$ and amyloid-${\mathsf{\beta }}_{1-42}$ peptides. The samples were prepared as multiple lipid bilayers on a silicon substrate. The in- and out-of-plane X-ray scattering is gathered in a 2-dimensional reciprocal space map with a point detector.
