  "experiment_description": "Synchrotron SAXS data from solutions of the C-terminal truncated ovine prion protein (94-234) with ARR polymorphism in 25 mM ammonium acetate, 250 mM NaCl, 0.001 mM CuSO4, pH 5.5 were collected using size exclusion chromatography SAXS (SEC-SAXS) on the BM29 beam line at the ESRF (Grenoble, France) using a Pilatus 1M detector at a sample-detector distance of 2.9 m and at a wavelength of λ = 0.099 nm (l(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). SEC-SAXS was performed at 20 °C using the following parameters: Column type, Superdex 200 5/150 GL (GE Healthcare); Flow rate: 0.15 mL/min; Total acquisition time: 25 min; Injection concentration: 7 mg/mL; Injection volume: 50 μL. The data obtained through the sample elution peak (873-925 1 s frames) were normalized to the intensity of the transmitted beam and radially averaged; the scattering of the solvent-blank was subtracted and the individual subtracted data sets were scaled and averaged to generate the scattering profile displayed in this entry.",
