Analytical Ultracentrifugation

In contrast to other methods used to analyze macromolecules, analytical ultracentrifugation (AUC) enables characterization of samples in their native state under biologically relevant solution conditions. AUC is the most versatile, rigorous and accurate technology available for determining the molecular weight, hydrodynamic and thermodynamic properties of a protein or other macromolecule. It can be used to investigate nearly any type of molecule or particle over a wide range of concentrations and in a diverse variety of solvents. For many research questions, there is no satisfactory analytical substitute for AUC.
