IDMethodpHTemperatureDetails
1VAPOR DIFFUSION, HANGING DROP300Protein was changed into crystallization buffer (20mM K-HEPES, pH7.5, 10% w/v glycerol, 0.2mM PMSF, 1mM DTT, 4mM Mg-ATP, 0.01% Na-Azide) and concentrated to 18 mg/ml. Crystallization was carried out by setting hanging drops containing 2 ul of protein, (diluted to 13.5mg/ml with 20mM K-Hepes, pH 7.5, 10% glycerol), 0.3 ul 70% glycerol and 1.8 ul of precipitant (20% PEG 4000, 200mM Ammonium sulfate, 100mM Bis-Tris, pH 5.5) over 500ml of the same precipitant solution. Crystals appeared within one day and were of dimensions up to 200 um., VAPOR DIFFUSION, HANGING DROP, temperature 300K
