1				1.0M Ammonium sulfate in water, pH 5.5, VAPOR DIFFUSION, HANGING DROP, temperature 292K. Protein stock was BACE MUT46B batch XII 8.5 mg/mL in 10mM Tris-HCl pH 7.4, 25mM NaCl, with a 5-fold excess of NVP-AFJ144-NX-2 added from a 50mM stock solution in 90% DMSO-D6 (1.8% DMSO in drop). A solution containing 1.2M Ammonium sulfate, 25% Glycerol, 1mM NVP-AFJ144-NX-2 and 1.8% DMSO was used as cryo-protectant
