1 | VAPOR DIFFUSION, HANGING DROP | 6 | HANGING DROPS. EQUAL VOLUMES OF 8 MG/ML PROTEIN AND RESERVOIR SOLUTION CONTAINING 0.1 M MES (PH 6.0), 18% (W/V) MONOMETHYLETHER PEG 5000, 0.01 M COCL2, AND 0.02% NA-AZIDE. CRYOPROTECTANT/SOAK SOLUTION CONTAINED 0.1 M MES (PH 6.0), 20% (W/V) MONOMETHYLETHER PEG 5000, 0.01 M COCL2, 20% GLYCEROL AND 0.005 M CELLOTETRAOSE. THE AXES OF THE CRYO-COOLED CRYSTALS ARE SYSTEMATICALLY SHORTER THAN THOSE OF CRYSTALS COLLECTED AT ROOM TEMPERATURE. IN ORDER TO KEEP THE SAME INDEXING AS IN PREVIOUS ROOM-TEMPERATURE DATA SETS, THE LONGER A-AXIS IS LISTED BEFORE THE SHORTER B-AXIS., vapor diffusion - hanging drop |
