Synchrotron SAXS data from a solution of bovine serum albumin (mixture) in 50 mM HEPES, pH 7.5, were collected on the EMBL-P12 beam line at the PETRA III storage ring (DESY, Hamburg, Germany) using a Pilatus 2M detector at a sample-detector distance of 3.1 m and at a wavelength of λ = 0.124 nm (l(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 2.25 mg/ml was measured at 10°C. 100 successive 0.050 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.

The data displayed in this entry represents the averaged 1D-SAXS profile obtained from 100 individual SAXS data frames. Included in the full entry zip-archive are each of the individual subtracted SAXS profiles as well as each individual sample and buffer frame (100 in total).
