Synchrotron SAXS data from solutions of von Willebrand factor D4N-CK, wildtype, in 20 mM HEPES, 150 mM NaCl, 1 mM CaCl2, 1 mM MgCl2, pH 7.5 were collected on the EMBL P12 beam line at PETRA III (DESY, Hamburg, Germany) using a Pilatus 6M detector at a sample-detector distance of 3 m and at a wavelength of λ = 0.124 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 2.70 mg/ml was measured at 20°C. 20 successive 0.200 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.
