1	VAPOR DIFFUSION, SITTING DROP	6.5	277.15	0.5 ul 64 mg/ml EFE-Y306A (1 mM manganese chloride, 25 mM HEPES pH 8.0, 1 mM TCEP, 3 mM L-Arginine, 3 mM 2-oxoglutarate) was mixed with 0.5 ul reservoir solution. The sitting drop reservoir of 200 ul contained 25% w/v Polyethylene glycol 3,350, 0.1 M Bis-Tris pH 6.5, 0.2 M sodium chloride. The crystal was soaked for five minutes in 25% w/v Ethylene glycol, 75% reservoir solution before freezing it.
