Review assay metadata, readout intent, target linkage, and publication context from the same page.

Binding
HTRF FRET Assay: Inhibitor compounds, prepared at 3× the desired final concentration in 1×BACE assay buffer (20 mM sodium acetate pH 5.0, 10% glycerol, 0.1% Brij-35) supplemented with 7.5% DMSO are pre-incubated with an equal volume of autoBACE-2 enzyme diluted in 1×BACE assay buffer (final enzyme concentration 1 nM) in black 384-well NUNC plates for 30 minutes at 30° C. The assay is initiated by addition of an equal volume of the QSY7-EISEVNLDAEFC-Eu-amide substrate (200 nM final concentration, Km=8 μM for 4 μM for autoBACE-2) prepared in 1×BACE assay buffer supplemented with 7.5% DMSO and incubated for 90 minutes at 30° C. DMSO is present at 5% final concentration in the assay. Following laser excitation of sample wells at 320 nm, the fluorescence signal at 620 nm is collected for 400 ms following a 50 μs delay on a RUBYstar HTRF plate reader (BMG Labtechnologies).
