1 | sitting drop | 5.5 | 292 | PROTEIN STOCK WAS BACE MUT46B (14-447)7.3MG/ML IN 10MM TRIS-HCL PH 7.4, 25MM NACL. CRYSTALLIZATION SOLUTION WAS 1.0M AMMONIUM SULFATE IN WATER (JBS 6 A2). CRYSTALS WERE GROWN BY VAPOR DIFFUSION IN SITTING DROPS IN 96-WELL CORNING MICROTITER PLATES. CRYO-PROTECTANT WAS 80% WELL SOLUTION, 20% 1,2-PROPANEDIOL. |
