Synchrotron SAXS data from solutions of Leucine-rich repeat and fibronectin type-III domain-containing protein 5 (fragment SALM5 (LRR-Ig)) in 30 mM Tris-Cl, 150 mM NaCl, 3% v/v glycerol, pH 7.5, were collected on the B21 beam line at the Diamond Light Source storage ring (Oxfordshire, UK) using a Pilatus 2M detector at a sample-detector distance of 4.0 m and at a wavelength of λ = 0.1005 nm (l(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). Solute concentrations ranging between 1 and 5 mg/ml were measured at 15°C. 18 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 concentration were merged with the highest concentration high angle data to yield the final composite scattering curve.
