Active BACE1 enzyme cleaves the substrate, causing the loss of energy transfer, and thus a reduction in SA-XL665 or Sa-d2 emissions.\u003c\/p\u003e\n\n\n\n\n  \u003cbr\u003e\n        \n\n\n\t\u003cbr\u003e\n  \u003cbr\u003e\n        \u003cbr\u003e\n  \n\n      \u003cbr\u003e\n  \u003cbr\u003e\n  \u003cbr\u003e\n    \u003cbr\u003e\n      \u003cbr\u003e\n        \u003cbr\u003e\n        \u003cbr\u003e\n        \u003cbr\u003e\n        \u003cbr\u003e\n      \u003cbr\u003e\n    \n\n    \u003cbr\u003e\n      \n\n      \u003cbr\u003e\n        \n\n      \u003cbr\u003e\n    \n\n  \n\n\n\n\n\u003cp\u003e \u003c\/p\u003e\n\n\n\n\n\u003cp\u003eAssay protocol\u003cbr\u003e\nThe assay is run in a two-step process: 1.BACE1 enzymatic reaction: Mix together the APP substrate, BACE1 and\/or compounds, then incubate (we recommend a time course study to determine the optimal stimulation time). 2.BACE1 activity detection: Add Streptavidin-XL665 or Streptavidin-d2.
