Figure 16. MULCh calculations of component X-ray and neutron contrasts.

Figure 16

The online web interface of the Contrast module of MULCh is shown. A. Defining the solvent. B. Defining the macromolecules of a sample. In this instance a complex of two proteins, one of which is deuterated and binds two calcium ions. C. The scattering length and contrast output table from Contrast that includes Δρ for SAXS and SANS. For SANS the magnitude of Δρ is calculated for increasing fractions of 2H2O in the solvent. The fraction of 2H2O required to obtain the component and whole complex match points (Δρ = 0) are reported.
