      Description
      OverviewAn internally quenched fluorogenic 11-mer peptide that acts as a sensitive and selective substrate for cathepsins D and E (kcat/Km = 15.6 µM-1s-1 and 10.9 µM-1s-1 for rat gastric cathepsin D and human erythrocyte cathepsin E, respectively), but not cathepsins B, H, or L . Cleavage occurs between Phe-Phe residues and results in enhanced fluorescence. A useful tool for inhibitors screening or for the determination of cathepsins D and E activities in crude extracts of various tissues and cell lysates.

      SynonymsMOCAc-GKPILF~FRLK(Dnp)-D-R-NH₂
      DescriptionAn internally quenched fluorogenic 11 amino acid peptide that acts as a sensitive and selective substrate for cathepsins D and E (kcat/Km = 15.6 µM-1s-1 and 10.9 µM-1s-1 for rat gastric cathepsin D and human erythrocyte cathepsin E, respectively). Does not act as a substrate for cathepsins B, H, or L. Cleavage occurs at the Phe-Phe amide bond resulting in enhanced fluorescence. Useful for screening cathepsin D and E inhibitors and for determining cathepsin D and E activity in tissue and cell extracts. Excitation max: ~328 nm; emission max: ~393 nm.
      FormYellow lyophilized solid
      FormulationSupplied as a trifluoroacetate salt.
