Synchrotron SAXS data from solutions of myelin basic protein in 20 mM NaH2PO4/Na2HPO4, 99.9% v/v D2O, pH 4.8 were collected on the BM29 beam line at the ESRF (Grenoble, France) using a Pilatus 1M detector at a wavelength of λ = 0.099 nm (l(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). 10 successive 2 second frames were collected at 10°C from a sample at 4.5 mg/ml. The data were normalized to the intensity of the transmitted beam and radially averaged; the scattering of the solvent-blank was subtracted.
