Data validation


There are no models related to this curve.

Synchrotron SAXS data from solutions of cytochrome C in 50 mM Tris, pH 7.4 were collected at the EMBL-P12 beam line at the PETRA III storage ring (Hamburg, Germany) using an Eiger 4M detector at a sample-detector distance of 1.6 m and at a wavelength of λ = 0.124 nm (I(s) vs s, where s = 4πsinθ/λ and 2θ is the scattering angle). One solute concentration of 2.00 mg/ml was measured at 20°C. A single 1.3 millisecond frame was collected. The data were normalized to the intensity of the transmitted beam and radially averaged; the scattering of the solvent-blank was subtracted and the data were scaled to the protein concentration.
