1	VAPOR DIFFUSION, SITTING DROP	6.5	277.15	0.2 ul 64 mg/ml EFE (+1 mM manganese chloride, 25 mM HEPES pH 8.0, 1 mM TCEP, +2.5 mM L-arginine) was mixed with 0.2 ul reservoir solution. The sitting drop reservoir of 50 ul contained 25% PEG 1500 and 0.1 M MMT buffer, pH 6.5. The crystal was soaked for about a minute in 25% w/v Polyethylene glycol 400, 75% reservoir solution before freezing it.
