1	VAPOR DIFFUSION, HANGING DROP	5.6	286	CRYSTALS WERE OBTAINED BY THE HANGING DROP VAPOR DIFFUSION METHOD AT 13 DEGREES C BY MIXING 1.5 MICROLITERS OF SOLUTION CONTAINING A 1:3 MOLAR RATIO OF PHOSPHORYLATED ROS1 KD (12.2MG/ML) TO CRIZOTINIB AND 1.5 MICROLITERS OF RESERVOIR SOLUTION CONTAINING 25% (W/V) PEG 3350, 0.6M POTASSIUM THIOCYANATE AND 0.1M SODIUM CITRATE TRIBASIC DIHYDRATE, PH5.6. CRYSTALS WERE FLASH-FROZEN IN LIQUID NITROGEN AFTER TRANSFER TO 2 MICROLITERS OF RESERVOIR SOLUTION CONTAINING 25% (V/V) GLYCEROL AS A CRYOPROTECTANT.
