| Figure 4 Comparison of neutron and X-ray scattering data with models of human immunoglobulin IgG4 composed of Fab and Fc regions (Rayner et al., 2014  ). (a) Atomistic structures of an extended asymmetric (left) and a compact asymmetric (right)
IgG4 model. In these, the Fc region is viewed in a similar orientation. (b), (c) Comparisons of the calculated scattering curves for sphere models generated by SCT from the atomistic models with neutron and X-ray experimental data, respectively.
The Q range is depicted from 0.2 to 1.6 nm−1. In both cases, the compact asymmetric model (blue curve: PDB code 4pto) gives good fits to the experimental data, whereas the extended model (red curve)
does not. |
