Table 1. Model-free SANS parameters of the heterododecameric and homododecameric complexes at 20C.
The forward scattered intensities I(0) and radii of gyration R g extracted from the Guinier ranges (Q min R g Q max R g; fits are shown as an inset in Fig. 4 ▶ a) are shown in comparison to the values extracted by indirect Fourier transform using GNOM (Svergun, 1992 ▶). The values extracted from both approaches are in very good agreement. The Guinier parameters were not determined for the 70% D2O data sets owing to high noise levels. The two GNOM R g values represent the direct/indirect-space values, respectively.
