General description

An internally quenched fluorogenic peptide substrate containing the C-terminal β-APP (amyloid β-peptide precursor protein) amino acid sequence that is cleaved by γ-secretase. Shown to be sensitive and useful for assaying γ-secretase activity. The proteolysis at the Aβ40-, Aβ42-, and Aβ43-generating cleavage sites results in enhanced fluorescence.
