Method pH Temprature Details
X-RAY DIFFRACTION 7.3 293 OBTAINED BY EQUILIBRATING A 2 UL DROP OF 1:1 PROTEIN:RESERVOIR AGAINST A 700 UL RESERVOIR CONTAINING 1.6-1.9 M DL-MALIC ACID (PH 7.3). FOR CRYOPROTECTION, 2 UL OF MOTHER LIQUOR CONTAINING 10% GLYCEROL WAS ADDED DIRECTLY TO THE DROP AND CRYSTALS WERE SERIAL TRANSFERRED INTO MOTHER LIQUOR SOLUTION CONTAINING 5, 7.5 AND 10% GLYCEROL. PRIOR TO FLASH FREEZING IN LIQUID NITROGEN, CRYSTALS WERE TRANSFERRED UNDER A LAYER OF OIL AND INCUBATED WITH CARBON MONOXIDE-SATURATED CRYOPROTECTANT FOR 15-45 MINUTES. CRYSTAL GROWTH AND MANIPULATION WAS PERFORMED ANAEROBICALLY.
