1	VAPOR DIFFUSION, SITTING DROP	6.29	293	TO 15 MG/ML BUB1, ATP WAS ADDED TO A FINAL CONCENTRATION OF 10 MM. SITTING DROPS WERE MADE BY MIXING 1.5 MICROLITERS PROTEIN WITH 1.5 MICROLITERS CRYSTALLIZATION SOLUTION (20% W/V PEG 3350, 0.1 M SODIUM FORMATE PH 6.29, 25 MM DTT) AND EQUILIBRATING AGAINST 200 MICROLITERS OF RESERVOIR SOLUTION. LARGE SINGLE CRYSTALS WERE OBTAINED BY REPEATED SEEDING. THE CRYSTALS WERE CRYO-PROTECTED IN RESERVOIR SOLUTION SUPPLEMENTED WITH 18% V/V GLYCEROL AND THEN FLASH-COOLED IN LIQUID PROPANE, VAPOR DIFFUSION, SITTING DROP, TEMPERATURE 293K, vapor diffusion, sitting drop
