Data validation

Synchrotron SAXS data from solutions of Human Albumin (P5) in 20 mM Tris, 150 mM KCl, 2% glycerol, pH 7.4 were collected on the 12.3.1 (SIBYLS) beam line at the Advanced Light Source (ALS) storage ring (Berkeley, CA, USA) using a Pilatus3 X 2M detector at a sample-detector distance of 2.1 m and at a wavelength of λ = 1.1127 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). In-line size-exclusion chromatography (SEC) SAS was employed. The SEC parameters were as follows: A 55.00 μl sample at 3 mg/ml was injected at a 0.50 ml/min flow rate onto a Shodex KW-800 series column at 20°C. 600 successive 3 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.
