High \(q\) (> 3 nm⁻¹) scattering profiles of Aβ-42 fibrils, modified and unmodified LGAB and BSA in the powder or flake forms measured from a monochromatic, low energy wide angle-X-ray scattering and c sSAXS. b The differences in the experimental set-ups of monochromatic WAXS and sSAXS are shown in the schematic. sSAXS covers the length scales of 0.25- 2.1 nm. All samples exhibit characteristics of cross-β motifs with reflections ~ \(q\)= 6.3 and 13.1 nm⁻¹
