ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	5.5	292	Crystals were grown from 12% (w/v) PEG 8,000, 0.1M KCl, 5% glycerol. Protein stock was 12.7mg/ml BACE in 10mM Tris-HCl pH 7.4, 25mM NaCl, with a 2-fold excess of compound added from a 50mM stock solution in DMSO (0.55% DMSO in drop). Before mounting, the crystals were briefly transferred to a cryo-protectant solution containing 12% (w/v) PEG 8,000, 0.5M KCl, 15% glycerol., VAPOR DIFFUSION, HANGING DROP, temperature 292K
