Abstract

Small‐angle X‐ray scattering (SAXS) has emerged as an important method for studying large‐scale dynamic processes, ranging from protein folding to virus particle polymorphism. The renaissance of this method has resulted from a variety of advances in molecular biology and X‐ray instrumentation, and these have dramatically increased the information content of the derived results. Modern synchrotron X‐ray sources and advanced detector systems have lead to higher‐resolution data in both the spatial and time domains. The purpose of this chapter is to address practical aspects of SAXS as they relate to and complement macromolecular crystallography.
