apo XMRV RT CRYSOL model

Synchrotron SAXS data from solutions of apo XMRV RT in 10 mM HEPES 100 mM KCl 5% Glycerol, pH 6.5 were collected on the EMBL X33 camera at the DORIS III storage ring (Hamburg, Germany) using a Pilatus 1M-W detector at a sample-detector distance of 2.7 m and at a wavelength of λ = 0.15 nm (l(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). 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.
