SAXS data from solutions of C-type lectins CTL4/CTLMA2 in 500 mM NaCl, 20 mM CHES, 0.5 mM CaCl2, 1% glycerol, pH 9 were collected on a Rigaku BioSAXS-2000 instrument at Thomas Jefferson University (Philadelphia, PA, USA) using a Pilatus 100K detector at a sample-detector distance of 0.481 m and at a wavelength of λ = 0.154187 nm (l(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 3.10 mg/ml was measured at 20°C. Six successive 300 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.
