Neutron reflectivity (plotted as log10R) as a function of momentum transfer (Q) for surface-deposited 7:3 d-POPC/POPS
(left) and 85:15 d-POPC/CL (right) phospholipid bilayers
in the absence (black, Figure 4) and presence
(color) of 4 μM d-α-synuclein. Reflectivity
was measured for three solvent contrasts: D2O (red circles),
CMSi (green triangles), and H2O (blue squares). CMSi and
H2O profiles are offset in log(R) by −2
and −1, respectively, for the sake of clarity.
