The radius of gyration, which is the most important structural parameter obtainable by small-angle X-ray scattering (SAXS), comprises the information of the inner structure of protein in solution as well as the bulk structure. The rough distribution of electron density is revealed by contrast variation measurement. Heavy atom labeling with contrast variation reveals the number of heavy atoms binding to the protein and the distribution of heavy atoms in the protein. In the case of the oligomeric protein, other than the radius of gyration of the whole molecule, the radius of gyration of a subunit and the distance between subunits are obtainable by SAXS. Some examples are also summarized.
