Data validation


There are no models related to this curve.

Synchrotron SAXS data from C-Tir in 20 mM sodium phosphate, 150 mM NaCl, 1 mM EDTA, pH 6.5 were collected on the BM29 beam line at the European Synchrotron Radiation Facility (Grenoble, France) using a Pilatus 1M detector at a sample-detector distance of 2.867 m and at a wavelength of λ = 0.09919 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). Solute concentrations 1, 2, 5, 7.5, 10 mg/ml were measured at 25°C, collecting 28 successive 2 second frames. The data were normalized to the intensity of the transmitted beam and radially averaged; the scattering of the solvent-blank was subtracted. The low angle data collected at lower concentration were merged with the highest concentration high angle data to yield the final composite scattering curve. No signs of radiation were damage detected.
