Data validation

There are no models related to this curve.

Synchrotron SAXS data from solutions of TIA-1 bound to TC1 DNA in 20 mM HEPES, 100 mM NaCl, 3% v/v glycerol, pH 7 were collected on the SAXS/WAXS beam line at the Australian Synchrotron (Melbourne, Australia) using a Pilatus3 S 2M detector at a sample-detector distance of 1.4 m and at a wavelength of λ = 0.10332 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 2.90 mg/ml was measured at 15°C. 30 successive 1 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.
