温度: 289 K / 手法: 蒸気拡散法, シッティングドロップ法 / pH: 8.5 詳細: (5mg/ml) HcGAS catalytic domain was mixed with 17/16 bp dsDNA in a molar ratio of 1:1.25 protein:DNA in a buffer containing 20 mM Tris pH 7.5, 150 mM NaCl, 10mM MnCl2, 1mM TCEP, 5mM AMPPNP ...詳細: (5mg/ml) HcGAS catalytic domain was mixed with 17/16 bp dsDNA in a molar ratio of 1:1.25 protein:DNA in a buffer containing 20 mM Tris pH 7.5, 150 mM NaCl, 10mM MnCl2, 1mM TCEP, 5mM AMPPNP and 1mM compound. Crystals were obtained with sitting drop vapor diffusion in drops mixed 1:1 with a reservoir of 0.1M Tris pH 8.0, 0.1 M Lithium Sulfate, 20% PEG 4000 and cGAS crystal seeds. Crystals were cryo-protected using reservoir solution supplemented with 25% ethylene glycol and flash-frozen in Liquid N2.
