温度: 277 K / 手法: 蒸気拡散法, シッティングドロップ法 / pH: 5.6 詳細: For crystallization, reservoir solutions were prepared by a Tecan robot and 200-nL crystallization drops were dispensed on 96x2-well MRC plates (Innovadyne) by a Cartesian (Genomic Solutions) ...詳細: For crystallization, reservoir solutions were prepared by a Tecan robot and 200-nL crystallization drops were dispensed on 96x2-well MRC plates (Innovadyne) by a Cartesian (Genomic Solutions) nanodrop robot at the High-Throughput Crystallography Platform of the Barcelona Science Park. Best crystals appeared in a Bruker steady-temperature crystal farm at 4C with protein solution (10 mg/mL in 50mM AMPSO pH9.0) and 20% PEG 8000, 0.1M (NH4)2SO4, 0.01M MgCl2, 0.05M MES pH5.6 as reservoir solution. These conditions were efficiently scaled up to the microliter range with 24-well Cryschem crystallization dishes (Hampton Research). Crystals were cryo-protected with 16% PEG 8000, 20% glycerol, 0.1M (NH4)2SO4, 0.01M MgCl2, 0.05M MES pH5.6. , VAPOR DIFFUSION, SITTING DROP, temperature 277K
