Data collection was performed at at 10°C. 255 successive 2.8 second frames were collected through an HPLC-SEC elution peak. 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 protein concentration, then averaged to produce the final SAXS profile displayed in this entry.",
