1	VAPOR DIFFUSION, SITTING DROP	7	289.15	0.2 uL 11 mg/mL MIF (100 mM Tris-HCl pH 8.0, 200 mM NaCl) were mixed with 0.2 uL of reservoir solution. Sitting drop reservoir contained 33 uL of 2.0 M Ammonium sulfate, 0.1 M HEPES pH 7.0, 3% Isopropanol and <5mM 4-(2-isothiocyanatoethyl)benzenesulfonamide (10% DMSO final). Crystal was frozen in a solution of ~25% Glycerol, 75% reservoir
