1	VAPOR DIFFUSION, SITTING DROP	6	289.15	0.2 ul 10.2 mg/ml FphI (20mM Tris pH 8.0, 150mM NaCl) were mixed with 0.2 ul of reservoir solution. Sitting drop reservoir contained 200mM Magnesium chloride hexahydrate, 100mM MES pH 6.0 and 20% w/v PEG 6000. Crystal appeared within a day at 16C and grew until day 2.5. Crystal was incubated for ~10s in a solution of ~25% glycerol, 75% reservoir prior to freezing.
