X-RAY DIFFRACTION

Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	5.6	?	CRYSTAL WERE GROWN AT ROOM TEMPERATURE FROM HANGING DROPS CONTAINING 62% SATURATED AMMONIUM SULFATE, 1.5% ISOPROPANOL AND 100 MM CACODYLATE, PH 5.6. DERIVATIZATION CONDITIONS: SOLID CHITOBIOSE WAS ADDED TO THE MOTHER LIQUOR TO MAKE UP HIGH CONCENTRATED STOCK SOLUTION, 0.5 TO 1.0 MICRO LITERS OF THE STOCK SOLUTION WERE ADDED TO THE CRYSTALLISATION DROP CONTAINING CRYSTALS. THE CRYSTALS WERE MOUNTED IMMEDIATELY IN GLASS CAPILLARY. EXPOSURE TIME WAS LIMITED TO 10 MINUTES OR LESS. THESE CRYSTALS: 4 MINS 50 SECS. THE CHITOBIOSE WAS SUPPLIED BY SIGMA., vapor diffusion - hanging drop
