Crystallization

Crystalization Experiments
Method Vapor Diffusion Hanging Drop
pH 7
Details BRIGHT YELLOW CRYSTALS WERE GROWN IN 24-WELL LINBRO PLATES USING HANGING DROP DIFFUSION METHOD AT ROOM TEMPERATURE. RESERVOIR: 1 ML CONTAINING 0.1M POTASSIUM PHOSPHATE AND 2M AMMONIUM SULFATE (PH 7.0). PRISM CRYSTALS TYPICALLY IN TWO WEEKS AT ROOM TEMPERATURE., vapor diffusion - hanging drop THE E3 DOMAIN (117-601) CRYSTALLIZES IN AMMONIUM SULFATE. IT INCLUDES A FAD COFACTOR BUT NOT THE NADH. THE E3 DOMAIN (117-601) CRYSTALLIZES IN AMMONIUM SULFATE. IT INCLUDE A FAD COFACTOR BUT NOT THE NADH.
