G-quadrupex DAMFILT model
Synchrotron SAXS data from solutions of G-quadruplex DNA from Hepatitis B virus (wild type) in 20 mM HEPES, 100 mM KCl, 1 mM EDTA, pH 7.5 were collected on the B21 beam line at the Diamond Light Source storage ring (Didcot, UK) using a Pilatus 2M detector at a sample-detector distance of 4 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. 620 successive 3 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.
