温度: 289 K / 手法: 蒸気拡散法, ハンギングドロップ法 / pH: 7 詳細: Native: Three microliters of protein solution [6.35mg/ml MidTm; 20mM Tris-HCl pH7.0; 100mM NaCl; 2mM 2-mercaptoethanol and 2mM NaN3] were combined with two microliters of 14% PEG2k-MME, and ...詳細: Native: Three microliters of protein solution [6.35mg/ml MidTm; 20mM Tris-HCl pH7.0; 100mM NaCl; 2mM 2-mercaptoethanol and 2mM NaN3] were combined with two microliters of 14% PEG2k-MME, and the resultant drop was equilibrated against 1ml reservoir solution [7.5% PEG2k-MME; 120mM NaCl; 24mM Tris-HCl pH7.0] by vapor diffusion at 16 C. Se-Met: Two microliters of protein solution [18mg/ml MidTm; 20mM Tris-HCl pH6.9; 100mM NaCl; 10mM mercaptoethanol and 2mM NaN3] were combined with two microliters of precipitant solution [28-32% PEG2K-MME; 50mM NaCl; 20mM Tris-HCl pH6.9 and 5mM mercaptoethanol]. The resultant mixture was equilibrated against 1ml reservoir solution [24% PEG2K-MME; 50mM NaCl; 20mM Tris-HCL pH6.9 and 5mM mercaptoethanol] by vapor diffusion at 16C. , VAPOR DIFFUSION, HANGING DROP, temperature 289K
