"description": "The HI sample (500 microlitres at 3.5 mg/ml) was injected onto a GE Healthcare S200 Increase 10/300 (24 ml) column at a flow rate of 0.1 ml/min at 23°C. A total of 120 x 30 second SAXS data frames were recorded throughout the HI elution. After background solvent corrections, SEC-SAXS data frames 71-83, corresponding to hexameric HI, were scaled, averaged and binned logarithmically to produce the data displayed in this entry. Additional files, including plots of the selected frames are included in the additional files of the full entry zip archive.",
