Data validation

There are no models related to this curve.

Synchrotron SAXS data from solutions of Toxin GraT in 50 mM Tris 250 mM NaCl 2 mM TCEP, pH 8 were collected using using size exclusion chromatography SAXS (SEC-SAXS) on the SWING beam line at SOLEIL (Saint-Aubin, France) using a Eiger 4M detector at a sample-detector distance of 1.5 m and at a wavelength of λ = 0.103317 nm (l(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). SEC-SAXS was performed at 25°C using the following parameters: Column: Shodex KW402.5-4F; Flow rate: 0.2 mL/min; Total acquisition time: 17 min; Sample injection concentration: 12.5 mg/mL; Injection volume: 40 μL. 40 successive 0.990 second frames were collected through the SEC elution profile. The data 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.
