α-Secretase Substrate II, Fluorogenic-Calbiochem

C₁₀₀H₁₄₄N₃₀O₂₀S

2118.47

An internally quenched fluorogenic peptide substrate that contains the α-secretase cleavage site of β-amyloid precursor protein (APP). Shown to be an effective substrate for yapsin-2, a glycosyl-phosphatidylinositol-linked aspartyl protease found in yeast (V_max/K_m = 0.031 min^-1). The cleavage has been shown to occur at the Lys-Leu bond. Excitation max: ~340 nm; emission max: ~490 nm.
