Figure 9
(a) The SANS curve of a BSA aggregate with considerable trivalent Y cations (200 mg ml−1 BSA and 30 mmol l−1 YCl3 at 35°C). The original measurement (blue) with incoherent scattering removed is displayed as black triangles and the corrected one as a red solid line. In the inset, the corresponding real-space correlation functions p(r) are shown. The real-space reconstructions are also added on the top right. (b) The logarithm of the real-space correlation function [\gamma\sim p(r)/r^{2}] for the BSA protein aggregate before and after the correction (black and red lines, respectively). Another example from a cruciferin complex (trimers at the oil droplet interfaces of an emulsion) is also shown, where the low-Q upturn is due to a high-Q cutoff of the scattering data. Here, the line indicates the correct extrapolation to [r\to 0].
