Fig. 3

a 1D SAXS plots showing q−2 dependence for ILLIIM (flat ribbon) and q−4 dependence for RNYIAQVD, b circular dichroism spectroscopy of the two peptide assemblies and c Thioflavin T spectroscopy to quantify the amount of amyloid formation of the two peptide assemblies. d WAXS spectra of ILLIIM and RNYIAQVD assemblies. SAXS and WAXS plots are shown as background subtracted against PBS in the same quartz capillary and averaged from approximately 15 recorded spectra.
