Crystallization Crystalization Experiments ID Method pH Temperature Details 1 VAPOR DIFFUSION, SITTING DROP 6.5 298 50mM magnesium acetate, 1.6M Lithium sulfate, 50mM MES pH 6.5. The crystal was crosslinked with 47.5 mg/mL EDC overnight, and then looped into a solution of 50mM potassium chloride, 4mM calcium chloride, 10% glycerol, and 10mM Tris hydrochloride for 1 hour. The drop was then supplemented with 100 micromolar bZip
