  Non-invasive light scattering methods provide data on biological
macromolecules (i.e. proteins, nucleic acids, as well as assemblies and larger
entities composed of them) that are complementary with those of size exclusion
chromatography, gel electrophoresis, analytical ultracentrifugation and mass
spectrometry methods. Static light scattering measurements are useful to
determine the mass of macromolecules and to monitor aggregation phenomena.
Dynamic light scattering measurements are suitable for the quality control and
to assess sample homogeneity, to determine particle size, examine the effect of
physical and chemical treatments, probe the binding of ligands, and study
interactions between macromolecules.
