Data validation


There are no models related to this curve.

Synchrotron SAXS data from solutions of ACTN2-G111V using SEC-SAXS (aggregate peak) in 20 mM HEPES, 150 mM NaCl, pH 8 were collected on the B21 beam line at the Diamond Light Source storage ring (Didcot, UK) using a Eiger 4M detector at a sample-detector distance of 3.7 m and at a wavelength of λ = 0.94 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 5.00 mg/ml was measured at 4°C. 600 successive 3.200 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.
