Synchrotron SAXS data from solutions of uPAR K50C-V70C in complex with uPA-ATF in 20 mM PBS, 5 %(v/v) glycerol, pH 7.4 were collected on the EMBL P12 beam line at PETRA III (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). Solute concentrations ranging between 0.3 and 2.5 mg/ml were measured at 10°C. 20 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 low angle data collected at lower concentrations were extrapolated to infinite dilution and merged with the higher concentration data to yield the final composite scattering curve.
