Figure 2. Sedimentation velocity analytical ultracentrifugation analysis of the quaternary structure of Vv-DHDPS in aqueous solution.

Figure 2

(A) Absorbance at 280 nm measured as a function of radial position from the axis of rotation (cm) for Vv-DHDPS (13 µM) centrifuged at 40,000 rpm. The raw data are presented as open symbols plotted at time intervals of 10 min overlaid with the 2DSA fit shown in panel B. (b) Pseudo-3D plots of solute distributions for 2DSA Monte Carlo of Vv-DHDPS using a grid resolution of 10,000 solutes. The colour scale represents the signal of each species in optical density units.
