Data validation

There are no models related to this curve.

Synchrotron SAXS data from solutions of the dsRBD1 and dsRBD2 domains of Drosophila helicase dosage compensation regulator, MLE, and the roX2 RNA stem-loop 7 18mer-fragment in 20 mM NaPO4, 200 mM NaCl, 1 mM DTT, pH 6.5 were collected on the BM29 beam line at the ESRF (Grenoble, France) using a Pilatus 1M detector at a sample-detector distance of 2.9 m and at a wavelength of λ = 0.09919 nm (l(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 1.00 mg/ml was measured at 20°C. 10 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.
