Figure 6
Scattering patterns of 20, 40 and 80 mg ml−1 BSA in salt solutions: A: 1 M CH3COONa; B: 1 M NaCl; C: 2 M (NH4)2SO4. The inset shows the ratio between two integrated intensities and , integrated over q1 = 0.5–0.8 nm−1 and q2 = 0.8–1.1 nm−1, respectively, each normalized by the average for that combination. This ratio highlights changes in the shape of the scattering patterns and thus serves as a simple indicator for the stability of the measurements over time. |
