Data validation


There are no models related to this curve.

Synchrotron SAXS data from solutions of C-terminal-binding protein 1 (CtBP1) bound to Retinoic acid-induced protein 2 (RAI2: 303-465) M1+M2 mutant L319A, S320A, L345A, S346A in 50 mM HEPES, 150 mM NaCl, 1 mM TCEP, 5% v/v glycerol, pH 7.2 were collected on the EMBL P12 beam line at the PETRA III storage ring (DESY; Hamburg, Germany) using a Pilatus 6M detector at a sample-detector distance of 4 m and at a wavelength of λ = 0.155 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 3.20 mg/ml was measured at 20°C. 40 successive 0.200 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.
