It was then adjusted to the required value of pH 6.3. If any slight turbidity occurred, it was removed by warming the solution. The solution was then filtered using a Millipore membrane/acetate cellulose acetate filter. This removes any nuclei which will encourage precipitation or formation of masses of small crystals. The solution was then warmed to 50 deg C by surrounding the test tube with preheated water in a Dewar. This allowed the solution to cool slowly to room temperature. The test tube was lightly sealed with cling film; crystals formed within a few days and were of suitable size for X-ray diffraction within two weeks; the test tube containing crystals was kept at 4 degC prior to data collection. The crystal used for data collection was about 0.2 mm3. PH range: 6.2 - 6.4 / Temp details: Room Temperature |

The EDNA strategy was used to obtain a start angle and 180 deg of data were collected with 0.1 deg oscillation and 0.1s exposure. The resolution of useful diffraction data achieved and used for structure analysis was 0.92 Angstrom. |
