experiment_description	Synchrotron SAXS data from solutions of rU30 in 1 mM Na-MOPS, 200 mM NaCl, 20 µM EDTA, pH 7 were collected on the G1 beam line at the Cornell High Energy Synchrotron Source (CHESS) storage ring (Ithaca, NY, USA) using a Finger Lakes CCD detector at a sample-detector distance of 2.0 m and at a wavelength of λ = 0.11 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). Solute concentrations ranging between 0.4 and 1.2 mg/ml were measured at 25°C. 30 successive 10 second frames were collected. The data were normalized to the intensity of the transmitted beam and radially averaged; the scattering of the solvent-blank was subtracted. The low angle data collected at lower concentrations were extrapolated to infinite dilution and merged with the higher concentration data to yield the final composite scattering curve.

Solute concentrations ranging between 0.4 and 1.2 mg/ml were measured at 25°C. 30 successive 10 second frames were collected. The data were normalized to the intensity of the transmitted beam and radially averaged; the scattering of the solvent-blank was subtracted. The low angle data collected at lower concentrations were extrapolated to infinite dilution and merged with the higher concentration data to yield the final composite scattering curve.",
