Data validation


There are no models related to this curve.

Synchrotron SAXS data from solutions of Myotilin Ig1Ig2 (250-444) in 20 mM Na+-HEPES, 150 mM, NaCl, 5 % v/v glycerol, 1 mM DTT, pH 7.4 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 = 0.099 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 14.12 mg/ml was measured at 20°C. The data were normalized to the intensity of the transmitted beam and radially averaged; the scattering of the solvent-blank was subtracted.
