1VAPOR DIFFUSION, SITTING DROP8277.150.5 ul 72 mg/ml EFE (25 mM HEPES pH 8.0, 1 mM TCEP) was mixed with 0.5 ul reservoir solution. The sitting drop reservoir of 200 ul contained 0.2 M lithium chloride, 0.1 M Tris-HCl pH 8.0, 20% w/v Polyethylene glycol 6,000. A grown crystal was soaked for 2 hours in a sitting drop containing 0.1 M nickel chloride, 0.2 M lithium chloride, 0.1 M Tris-HCl pH 8.0, 20% w/v Polyethylene glycol 6,000, the reservoir of 100 ul contained 0.2 M lithium chloride, 0.1 M Tris-HCl pH 8.0, 20% w/v Polyethylene glycol 6,000.The crystal was direcly frozen.
