Monte Carlo modeling of small-angle scattering data from non-interacting homogeneous and heterogeneous particles in solution.

A Monte Carlo algorithm that rapidly generates the scattered intensity function for complex heterogeneous particles is described. The heterogeneous particles are built from any number and orientation of simple building blocks, which include ellipsoidal shells, hollow ellipsoidal cylinders, ellipsoidal helices, triangular prisms, rectangular prisms, and semi-ellipsoidal shells. Applications are discussed such as real proteins and their complexes, polysaccharides, void effects on I(q), Guinier range estimation, and calculation of Stuhrmann plots.

Advances in structure analysis using small-angle scattering in solution.

The resolution and reliability of solution scattering models have been significantly improved by ab initio shape and domain structure determination, and by detailed modelling of macromolecular complexes using rigid-body refinement. Substantial progress has also been made in the quantitative analysis and modelling of assembly and folding processes, and intermolecular interactions.
