Data validation

There are no models related to this curve.

Synchrotron SAXS data from solutions of early E1A protein in 20 mM sodium phosphate pH 7.0, 200 mM NaCl, 1mM DTT, pH 7 were collected on the SWING beam line at SOLEIL (Saint-Aubin, France) using a Eiger 4M detector at a sample-detector distance of 2 m and at a wavelength of λ = 0.1033 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 5.60 mg/ml was measured at 10°C. 40 successive 0.900 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.
