Comparison of structures of Aβ-42 fibrils, modified and unmodified LGAB and BSA using solution SAXS. a, d 1D scattering profiles where the solid lines are calculated scattering profiles where fibrils are modeled as elliptical cylinders and proteins dissolved in pH 2 and 7 are modeled as ellipsoids. The Y-axis of the curves are scaled for better visualization. b, e Normalized pair distance distribution (\(p(r)\)) functions calculated from inverse Fourier transforms of 1D scattering profiles without model predictions. c, f Kratky plots of LGAB and BSA fibrils compared with their proteins dissolved at pH 7 prior to modifications
