Mca-SEVNLDAEFR-K(Dnp)-RR-NH2 is a fluorogenic substrate designed for the quantification of β-secretase (BACE) activity. When cleaved by BACE, it liberates 7-methoxycoumarin-4-acetyl (Mca), a compound whose fluorescence, with excitation and emission peaks at 328 nm and 420 nm respectively, serves as a measurable indicator of BACE enzymatic action.
