"description": "The data displayed in this entry show the averaged scattering intensity derived from of two independent SEC-SAXS measurements (a 50 µl and 100 µl injection, respectively). The full entry archive contains the unsubtracted 1D-data frames spanning both individual SEC-SAXS runs, in addition to the respective processed SEC-SAXS data for each run, prior to scaling and averaging.

"experiment_description": "Synchrotron SAXS data from solutions of 2A protein in 20 mM HEPES pH 7.4, 1 M KCl, 2% v/v glycerol, 1 mM DTT, were collected on the EMBL P12 beam line at PETRA III (DESY; Hamburg, Germany) using a Pilatus 6M detector at a sample-detector distance of 3 m and at a wavelength of λ = 0.123983 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 50.00-100 μl sample at 4.0 mg/ml were injected at a 0.35 ml/min flow rate onto a GE Superdex 75 Increase 5/150 column at 20°C. 143 successive 0.250 second frames were collected through two consecutive SEC-SAXS runs, spanning the sample elution peaks of the protein. The data were normalized to the intensity of the transmitted beam and radially averaged; the scattering of the solvent-blank was subtracted.",
