Native membranes containing two-dimensional crystals of the membrane-protein bacteriorhodopsin were fused into giant (10μm) single-crystalline patches and stacked to form perfect orientationally aligned multilayers. The diffuse scattering indicates a conformal buckling of the membranes on length scales of a few hundred angstroms. Analysis of the truncation rods allows us to elucidate the intermembrane correlations of the proteins at different hydration levels of the multilayer.enjournal_article10.1103/PhysRevLett.81.24940000760731000243144523x-ray scatteringmembrane biophysics
