Synchrotron SAXS data from solutions of single stranded poly-deoxyadenosine DNA (30mer, dA30) in 1mM Na MOPS, 20mM NaCl, pH 7 were collected on the G1 Beamline camera on the storage ring CHESS (Ithaca, USA) using a CCD Finger Lakes CCD detector at a sample-detector distance of 1.8 m and at a wavelength of λ = 0.1 nm (I(s) vs s, where s = 4π sin θ/λ and 2θ is the scattering angle). Solute concentrations ranging between 0.5 and 1.8 mg/ml were measured . 20 successive 10 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 and the different curves were scaled for sample concentration. The low angle data collected at lower concentrations were merged with the higher concentration data to yield the final composite scattering curve.
