1	VAPOR DIFFUSION, SITTING DROP	8	277.15	0.5 ul 72 mg/ml selenomethionine containing EFE (9 mM manganese chloride, 25 mM HEPES pH 8.0, 1 mM TCEP) was mixed with 0.5 ul reservoir solution of 10 mM N-omega-hydroxy-L-arginine, and 0.2 uL of 100 mM 2OG. The sitting drop reservoir of 200 ul contained 20% w/v Polyethylene glycol 6,000, 0.1 M Tris pH 8.0, 0.2 M Lithium chloride. The crystal was soaked for about a minute in 25% w/v ethylene glycol, 75% reservoir solution before freezing it.
