Synchrotron SAXS data from solutions of ApoE2 bound to 37 µg/mL heparin in 20 mM HEPES, 300 mM NaCl, 1 mM TCEP, pH 8 were collected on the B21 beam line at the Diamond Light Source (Didcot, UK) using a Pilatus 2M detector at a sample-detector distance of 4.0 m and at a wavelength of λ = 0.1 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 4.00 mg/ml was measured at 20°C. 28 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.
ApoE2 + 37 µg/mL heparin. Molecular weight estimates are inaccurate due to heparin heterogeneity.
