Synchrotron SAXS data from solutions of Immediate Early 3 DNA (ICP4N IE3_19mer) in 20 mM HEPES, 150 mM NaCl, pH 7.4, were collected using HPLC SEC-SAXS at the BM29 beam line at the ESRF (Grenoble, France) using a Pilatus 1M detector at a sample-detector distance of 2.9 m and at a wavelength of λ = 0.0992 nm (I(s) vs s, where s = 4π sin θ/λ and 2θ is the scattering angle). The sample was separated using a Superdex 200 increase 3.2/300 size exclusion chromatography column before exposure to X-rays. 50 µL of IE3_19merwas loaded onto the Superdex column and the eluent was flowed through the SAXS beam at 0.075 mL/min; the buffer used as the background was collected after one SEC column volume. Data were collected at 20°C at one second intervals.
