Synchrotron SAXS data from solutions of proliferating cell nuclear antigen (PCNA) in 20 mM Tris-HCl pH 7.5, 100 mM NaCl, 1 mM DTT were collected on the BM29 beam line at the ESRF (Grenoble, France) using a Pilatus 1M detector at a sample-detector distance of 2.9 m and at a wavelength of λ = 0.0998 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 1.50 mg/ml was measured at 10°C. 10 successive 1 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.
