Presentation #1:

Studying Macromolecules in Mixtures using Mechanical Marvels

Abstract: The most pressing questions in basic research revolve around the behavior of biological macromolecules in their native milieu. Many times, these macromolecules are assembled within a larger macromolecular assembly that is a composite of not only protein, but also nucleic acid, carbohydrate, or lipid.

In this session, we will review how AUC can accelerate basic research and enhance the information gathered from complementary structural and biophysical techniques, including X-ray crystallography and cryo-EM, light scattering, and small-angle X-ray and neutron scattering (SAXS/SANS).

Presentation #2:

Using Sedimentation Equilibrium to study the stoichiometry and binding affinity of macromolecular complexes.

Abstract: Sedimentation Equilibrium Analytical Ultracentrifugation (SE-AUC) is a powerful technique for studying protein-protein interactions in solution. In this presentation, I will show how SE-AUC was used to study the oligomeric state of a self-associating protein and to also resolve the stoichiometry of macromolecular hetero-complex. The considerations for experimental design will also be discussed.
