Small angle neutron scattering for the structural study of intrinsically disordered proteins in solution: a practical guide.

Small angle neutron scattering (SANS) allows studying bio-macromolecular structures and interactions in solution. It is particularly well-suited to study structural properties of intrinsically disordered proteins (IDPs) over a wide range of length-scales ranging from global aspects (radii of gyration and molecular weight) down to short-distance properties (e.g., cross-sectional analysis). In this book chapter, we provide a practical guide on how to carry out SANS experiments on IDPs and discuss the complementary aspects and strengths of SANS with respect to small angle X-ray scattering (SAXS).
