NUTS and BOLTS: Applications of fluorescence-detected sedimentation

Analytical ultracentrifugation is a widely used method for characterizing the solution behavior of macromolecules. However, the two commonly used detectors, absorbance and interference, impose some fundamental restrictions on the concentrations and complexity of the solutions that can be analyzed. The recent addition of a fluorescence detector for the XL-I analytical ultracentrifuge (AU–FDS) enables two different types of sedimentation...
