(A) Given here is the hydrodynamic radius (Rh) distribution and (C) sedimentation coefficient (s20,w) distribution of HMGA2 (coral), RF (cyan), and complex (sea green) at 1 mg/mL, suggesting monodisperse samples. (B) The Rh for HMGA2 and RF is plotted at multiple concentrations (1–10 mg/mL, bottom x axis) and for the complex between 0.2 and 1 mg/mL (top x axis). The vertical error bars indicate the SD from five measurements. (D) The Svedberg coefficient in water (s20,w) was plotted at multiple concentrations (0.2–2 mg/mL) for each sample with vertical error bars indicative of the SE from multiple scans. This plot presents the concentration independence of all samples under the experimental conditions. To see this figure in color, go online.
