Synchrotron SAXS data from solutions of Human Filamin A Ig-like domains 20-21* truncation (2141-2329) in complex with migfilin peptide in 20 mM Tris 50 mM NaCl 10mM DTT, pH 8 were collected on the BM29 beam line at the ESRF storage ring (Grenoble, France) using a Pilatus 1M detector at a sample-detector distance of 2.4 m and at a wavelength of λ = 0.93 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). Solute concentrations ranging between 1 and 4 mg/ml were measured . 10 successive 1 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 low angle data collected at lower concentration were merged with the highest concentration high angle data to yield the final composite scattering curve.
