1	VAPOR DIFFUSION, SITTING DROP	5.5	298	4 uL drop of protein solution [8-10 mg/mL EIZS, 20 mM Tris-HCl (pH 7.5), 300 mM NaCl, 10 mM MgCl2, 10% glycerol, 2 mM TCEP, 2 mM sodium pyrophosphate, and 2 mM benzyltriethylammonium chloride] was added to 4 uL of precipitant solution [100 mM Bis-Tris (pH 5.5), 25-28%polyethylene glycol 3350, and 0.2M(NH4)2SO4] and equilibrated against a 1 mL well reservoir of precipitant solution. Crystals appeared within 2-3 days. Then the crystals were soaked in a chelation buffer [5 mM 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid, 15 mM ethylenediaminetetraacetic acid, 100 mM Bis-Tris (pH 5.5), 30% polyethylene glycol 3350, 200 mM (NH4)2SO4, 15% glycerol] for 7 days. , VAPOR DIFFUSION, SITTING DROP, temperature 298K
