Synchrotron SAXS data from solutions of N-cadherin extracellular domains EC1-EC5 in 10 mM HEPES, 150 mM NaCl, 3 mM CaCl2, 0.02% NaN3, pH 8 were collected on the 13A beam line at the Taiwan Photon Source (NSRRC; Hsinchu, Taiwan) using a Eiger X 1M and Eiger X 9M detector at a sample-detector distance of 2.9 m and at a wavelength of λ = 0.0827 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 100.00 μl sample at 10 mg/ml was injected at a 0.10 ml/min flow rate onto a Agilent Bio SEC-3, 300 Å column at 13°C. Four successive 2 second frames were collected through the SEC sample peak. The data were normalized to the intensity of the transmitted beam and radially averaged; the scattering of the solvent-blank was subtracted.
