  • DIAROMATIC AMINO ACID SUBSTRATE FOR CATHEPSIN DETECTION
    Publication number: 20150293106
    Abstract: The present invention relates to a diaromatic amino acid substrate for cathepsin detection. When the substrate used for cathepsin detection is a polymer resulting from the binding of a protease-preferred amino acid and quencher to a diaromatic amino acid, cathepsin can be detected sensitively and accurately by fluorescence because cathepsin causes the protease-preferred amino acid and quencher to dissociate from the diaromatic amino acid, and fluorescence is recovered during this time.
