Figure 10
SWAXS data measured at TPS 13A for BSA (top), lysozyme (middle) and hemoglobin (bottom); also shown are the corresponding crystal structures. The sample concentrations are all 10 mg ml−1. With 100 µl injection volume, the peak sample concentration during the HPLC elution reduces to ca 4 mg ml−1 (cf. the dilution factors shown in Fig. S6). The WAXS data of BSA (Fig. S7) are replaced by those measured with the bypass mode (of little sample elution dilution effect) for better statistics. The intensity profiles of lysozyme and hemoglobin are, respectively, scaled down from the absolute intensity scales by factors of 50 and 500. Also shown are the fitting curves calculated using CRYSOL (dotted red curves) based on the crystal structures with PDB ID 3v03 for BSA, 1lyz for lysozyme and 1a3n for hemoglobin. The lower inset shows the fitting residual Δ/σ defined by the differences (Δ) of the model and experimental results normalized by the corresponding data uncertainties or errors σ (Trewhella et al., 2017). |
