Synchrotron SAXS data from solutions of Full-length Retinoic acid receptor RXR-alpha in complex with Ramp2 DNA in 20 mM Tris, 50 mM NaCl, 50 mM KCl, 5% glycerol, 2 mM Chaps, and 5 mM DTT, pH 7.5 were collected on the EMBL X33 beam line at the DORIS III, DESY storage ring (Hamburg, Germany) using a Pilatus 2M detector at a sample-detector distance of 2.7 m and at a wavelength of λ = 0.15 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 1.00 mg/ml was measured at 10°C. Eight successive 15 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.
