Analytical ultracentrifugation (AUC) is a powerful technique for analyzing fundamental characteristics of macromolecules in solution, including size and shape, assembly state, and degree of polydispersity. It allows the study of conformational changes and complex formation in physiologically relevant buffers. AUC is useful as a method to characterize structural aspects of macromolecules and as a quantitative technique that provides access to detailed thermodynamic characterization of a system under study.
Beckman Coulter is sponsoring a new educational webinar, “Analytical ultracentrifugation as a complementary technique for structural analysis of proteins and macromolecular complexes,” which will describe basic principles underlying sedimentation velocity and sedimentation equilibrium AUC methods and ways in which AUC can be used to complement crystallographic or other structural biology approaches. Examples will be provided to illustrate AUC approaches for characterization of monodisperse or assembling proteins, simultaneous size-and-shape analysis of multi-species mixtures, and determination of affinity and stoichiometry of macromolecular complexes.
Andrew Herr, PhD, is an Associate Professor in the Divisions of Immunobiology and Infectious Diseases and the Center for Systems Immunology at Cincinnati Children’s Hospital Medical Center. Dr. Herr’s laboratory uses a combination of analytical ultracentrifugation, X-ray crystallography and a wide array of biophysical techniques to analyze the structure and function of proteins involved in bacterial pathogenesis and the host immune response. The Herr lab has used AUC to study proteins that range in size from small polypeptides to massive antibody immune complexes, integral membrane proteins, intrinsically disordered proteins, and complicated assembling systems. They have also worked with biotech and pharma companies to analyze protein samples and help guide formulation decisions. Dr. Herr has authored over 50 published manuscripts and book chapters, with over half of these involving AUC analyses.
The complementary webinar, hosted by LabRoots, will be presented on August 13, 2015, at 8:00am PT, 11:00am ET, 3:00pm GMT.
