The protein was crystallized at 13 mg/ml in the following buffer 25 mM Tris/HCl pH 7.6, 2 mM dithiothreitol, 10% (v/v) glycerol. Drops of 0.7 ul protein with 0.7 ul of crystallisation solution were applied on the shelf. Crystals were soaked in the crystallisation solution supplemented with 30% (v/v) ethylene glycol for few seconds before freezing in liquid nitrogen. Temp details: +/- 3 degrees |
