Accounting for Photophysical Processes and Specific Signal Intensity Changes in Fluorescence-Detected Sedimentation Velocity
Fluorescence detected sedimentation velocity (FDS-SV) has emerged as a powerful technique for the study of high-affinity protein interactions, with hydrodynamic resolution exceeding that of diffusion-based techniques, and with sufficient sensitivity for binding studies at low picomolar concentrations. For the detailed quantitative analysis of the observed sedimentation boundaries, it is necessa...
متن کاملAnalysis of Protein Interactions with Picomolar Binding Affinity by Fluorescence-Detected Sedimentation Velocity
The study of high-affinity protein interactions with equilibrium dissociation constants (KD) in the picomolar range is of significant interest in many fields, but the characterization of stoichiometry and free energy of such high-affinity binding can be far from trivial. Analytical ultracentrifugation has long been considered a gold standard in the study of protein interactions but is typically...
متن کاملAnalytical ultracentrifugation: sedimentation velocity and sedimentation equilibrium.
Analytical ultracentrifugation (AUC) is a versatile and powerful method for the quantitative analysis of macromolecules in solution. AUC has broad applications for the study of biomacromolecules in a wide range of solvents and over a wide range of solute concentrations. Three optical systems are available for the analytical ultracentrifuge (absorbance, interference, and fluorescence) that permi...
متن کاملDrug-induced Changes in DMA Fluorescence Intensity Detected by Flow Microfluorometry and Their Implications for Analysis of DNA Content Distributions
Chicken erythrocytes, which contain less DNA than mammalian diploid cells, were used as an internal stan dard to control instrumental and staining variables during flow microfluorometric analysis. With the DNA stain, mithramycin, and with an EPICS II flow microfluorometer, ratios between the modal G, fluorescence of experimental cells and that of chicken erythrocytes were determined. The result...
