1VAPOR DIFFUSION, HANGING DROP8298Hanging drops comprised 2 ul of 14 mg/mL protein solution and 2 ul of well buffer (21% (w/v) PEG 8000, 0.17 mM (NH4)2SO4, 85 mM Tris-HCl, pH 8.0, and 10% Glycerol) that was present in the reservoir. Crystal complexes with inhibitors were formed in a soaking buffer (25% (w/v) PEG 8000, 0.17 mM (NH4)2SO4, 85 mM Tris-HCl, pH 8.0, 20% Glycerol)
