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. Excitation max.: ~355 nm; emission max.: ~440 nm.
