experiment_descriptionSynchrotron SAXS data from solutions of Ribonuclease E from Escherichia coli in 10 mM DTT, 10 mM MgCl2, 0.5 M NaCl, 20 mM Tris, pH 8 were collected on the B21 beam line at the Diamond Light Source (Oxfordshire, UK) using a Pilatus 2M detector at a sample-detector distance of 4.0 m and at a wavelength of λ = 0.1 nm (l(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 6.58 mg/ml was measured at 15°C. 640 successive 3 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.

One solute concentration of 6.58 mg/ml was measured at 15°C. 640 successive 3 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.",
