Synchrotron SAXS data from solutions of Full-length polypyrimidine tract binding protein (PTB) in 25 mM Tris, 250 mM NaCl, 2 mM DTT, pH 7.2 were collected on the EMBL X33 beam line at the DORIS III storage ring (Hamburg, Germany) using a 1D Gas detector detector at a sample-detector distance of 2.4 m and at a wavelength of λ = 0.15 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). Solute concentrations ranging between 3.4 and 20 mg/ml were measured at 25°C. 12 successive 60 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.
