Diluted TR-FRET Assay: TR-FRET Assay: The beta -secretase enzyme used in the TR-FRET is prepared as follows:The cDNA for the soluble part of the human (3-Secretase (AA 1-AA 460) was cloned using the ASP2-Fc10-1-IRES-GFP-neoK mammalian expression vector. The gene was fused to the Fc domain of IgG1 (affinity tag) and stably cloned into HEK 293 cells. Purified sBACE-Fc was stored in -80 C. in 50 mM Glycine pH 2.5, adjusted to pH 7.4 with 1 M Tris and had a purity of 40%.The enzyme (truncated form) was diluted to 6 ug/mL (stock 1.3 mg/mL) and the TruPoint BACE1 Substrate to 200 nM (stock 120 uM) in reaction buffer (NaAcetate, chaps, triton x-100, EDTA pH4.5). Enzyme and compound in dimethylsulphoxide (final DMSO concentration 5%) was mixed and pre-incubated for 10 minutes at RT. Substrate was then added and the reaction was incubated for 15 minutes at RT. The reaction was stopped with the addition of 0.35 vol Stop solution (NaAcetate, pH 9).
