1 | VAPOR DIFFUSION, HANGING DROP | 4.7 | 308 | CRYSTALS OF MURINE DELTA114 INOS WERE PREPARED IN THE PRESENCE OF IMIDAZOLE FOLLOWING THE PROCEDURES OF CRANE ET AL. (REFERENCE 3) AS FOLLOWS: THE 6 UL CRYSTALLIZATION DROPS CONTAINED 20 MG/ML MURINE DELTA114 INOS, 20 MM HEPES PH 7.6, 5 % GLYCEROL, 0.5 MM DTT, 6.8 % PEG-3350, 60 MM NA2SO3, AND 50 MM IMIDAZOLE/ MALATE BUFFER PH 4.7 WERE PLACED OVER A 1 ML RESERVOIR CONTAINING 13.6 % PEG-3350, 120 MM NA2SO3, AND 100 MM IMIDAZOLE/MALATE BUFFER PH 4.7. THESE CRYSTALS WERE SOAKED FOR 25 HOURS IN 5 UM 4-(Benzo[1,3]dioxol-5-yloxy)- 2-(4-imidazol-1-yl-phenoxy)-pyrimidine, 14 % PEG-3350, 1 MM NAN3, 50 MM MES PH 6.5 AND 50 MM NA2SO3. THE, pH 4.70, VAPOR DIFFUSION, HANGING DROP, temperature 308K |
