Crystalization Experiments
IDMethodpHTemperatureDetails
1VAPOR DIFFUSION, HANGING DROP6.6293N9 crystals were grown by hanging-drop vapour diffusion against a reservoir of 1.9M potassium phosphate, pH 6.8, starting with equal volumes of N9 NA (10-15 mg/ml in water) and potassium phosphate buffer 1.4M KH2PO4:3M K2HPO4 in ratio 8:4, pH 6.6 at 20 degrees celsius. Inhibitor complexes obtained by soaking N9 crystals in a solution of 1.4M potassium phosphate buffer, pH 6.8, containing 5mM of inhibitor for 3 hours at 4 degrees celsius. Soaked in glycerol cryo-buffer.
