Synchrotron SAXS data from solutions of CELSR1 ECR without calcium in 10 mM Tris, 150 mM NaCl, pH 8.5 were collected on the BioCAT 18ID beam line at the Advanced Photon Source (APS), Argonne National Laboratory (Lemont, IL, USA) using a Eiger2 XE 9M detector at a sample-detector distance of 3.7 m and at a wavelength of λ = 0.1033 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 250.00 μl sample at 0.9 mg/ml was injected at a 0.60 ml/min flow rate onto a GE Superose 6 Increase 10/300 column at 22°C. 2500 successive 0.600 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.
