Synchrotron SAXS data from solutions of the Gemin2/Survival Motor Neuron-like protein 1 (SMN1) complex from Schizosaccharomyces pombe, 0.422 g/L in 150 mM NaCl, 20 mM HEPES, 1 mM DTT, pH 7.5 were collected on the BM29 beam line at the ESRF storage ring (Grenoble, France) using a Pilatus 1M detector at a sample-detector distance of 2.9 m and at a wavelength of λ = 0.09919 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). In-line size-exclusion chromatography (SEC) SAS was employed. The SEC parameters were as follows: A sample at 1.3 mg/ml was injected at a 1.00 ml/min flow rate onto a GE Superdex 200 10/300 column at 20°C. 1800 successive 1 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.

For this entry, frame 739 was individually chosen and background subtracted using CHROMIXS. Concentration at this frame was determined from the UV280 trace, and was found to be 0.422 g/L (11.9 µM).
