X-RAY DIFFRACTION 6.50 293 CRYSTALS WERE GROWN IN ABOUT 2 WEEKS BY HANGING-DROP VAPOR DIFFUSION AT 293K. THE RESERVOIR WAS 0.2M MG ACETATE, 20% PEG 8K, 0.1M NA CACODYLATE PH 6.5. THE DROPS WERE 1.5MICROL OF 11.7 MG/ML PROTEIN, 0.05M HEPES, PH 7.0, PLUS 1.5MICROL OF RESERVOIR SOLUTION. A CRYSTAL WAS CRYOPROTECTED BY GRADUAL INCREMENTAL SOAKING IN RESERVOIR SOLUTION MIXED WITH GLYCEROL. THE CONCENTRATION OF GLYCEROL WAS INCREASED FROM 0 TO 30% IN 2-3% INCREMENTS DURING 2 HOURS. THE CRYSTAL WAS THEN FROZEN IN THE CRYOSTREAM.
