ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	7	294.15	0.6 uL ~24 mg/ml LarE (100 mM Tris-HCl pH 7.5, 300 mM NaCl) mixed with 1.2 uL of reservoir solution. Hanging drop reservoir contained 100 uL of 25% v/v pentaerythritol ethoxylate (15/4 EO/OH), 50 mM MOPS pH 7.0, 100 mM ammonium sulfate. Crystal soaked 5 minutes in ~20 mM cobalt sulfate, 30% v/v pentaerythritol ethoxylate (15/4 EO/OH), 50 mM BIS-TRIS pH 6.5, 50 mM ammonium sulfate
