(A) RSoXS data for BSA in PBS at 285.3 eV and CRYSOL-predicted scattering profile from aromatic carbons of BSA.
(B) RSoXS data for BSA in PBS at 288.3 eV and predicted scattering (summed) from a combination of the peptide backbone (backbone), all carbon atoms (C only), and non-carbon atoms on the side chains (side chains, non C) of BSA. The individual contributions to the total predicted scattering are determined from the relative X-ray absorbance of BSA.
