Synchrotron SAXS data from solutions of DH-PH - Dbl-homology domain (DH) and Pleckstrin-homology (PH) of Bcr-Abl tyrosine kinase p210 in 25 mM Tris-HCl, 150 mM NaCl, 5% Glycerol, 1 mM DTT, pH 7.5 were collected on the EMBL P12 beam line at the PETRA III storage ring (DESY; Hamburg, Germany) using a Pilatus 2M 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). Solute concentrations ranging between 1.8 and 14.4 mg/ml were measured at 20°C. 20 successive 0.045 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 concentration were merged with the highest concentration high angle data to yield the final composite scattering curve.
