SAXS data from solutions of SS DNA Aptamer 1 which binds Mtb GntR Homolog [Rv0792c_1] in 25 mM HEPES Buffer; 400 mM NaCl, pH 7.2 were collected at Anton Paar SAXSpace, CSIR - Institute of Microbial Technology (IMTech) using a Mythen 1K detector at a sample-detector distance of 0.3 m and at a wavelength of λ = 0.15414 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 1.50 mg/ml was measured at 10°C. Three successive 3600 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.
