Carbonic Anhydrase from in-house SEC-SAXS

Data type: SASBDB experimental data Status: Published Curve type: SEC-SAS Last updated: 2019-12-06T13:07:15.624532+01:00

The CAH sample (500 microlitres at 5.4 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 165 x 30 second SAXS data frames were recorded throughout the CAH elution. After background solvent corrections, SEC-SAXS data frames 96-105, corresponding to monomeric CAH, were scaled, averaged and binned logarithmically to produce the data displayed in this entry. Additional files, including plots of the selected frames and of I(0), HPLC and exposure cell UV traces and Rg vs. time (determined by AUTORG) are included in the additional files of the full entry zip archive.

A total of 165 x 30 second SAXS data frames were recorded throughout the CAH elution. After background solvent corrections, SEC-SAXS data frames 96-105, corresponding to monomeric CAH, were scaled, averaged and binned logarithmically to produce the data displayed in this entry. Additional files, including plots of the selected frames and of I(0), HPLC and exposure cell UV traces and Rg vs. time (determined by AUTORG) are included in the additional files of the full entry zip archive.",
