Z-(L-Arg)-AMC is a fluorogenic substrate for trypsin, cathepsin B, and cathepsin H.1,2Upon enzymatic cleavage by trypsin, cathepsin B, or cathepsin H, 7-amino-4-methylcoumarin (AMC) is released and its fluorescence can be used to quantify trypsin, cathepsin B, and cathepsin H activity. AMC displays excitation/emission maxima of 340-360/440-460 nm, respectively. 1.Zimmerman, M., Ashe, B., Yurewicz, E.C., et al.Sensitive assays for trypsin, elastase, and chymotrypsin using new fluorogenic substratesAnal.

Mca-KPLGL-Dap(Dnp)-AR-NH2 serves as a fluorogenic substrate specifically designed for matrix metalloproteinases (MMPs). This compound facilitates the quantification of MMP activity by releasing 7-methoxycoumarin-4-acetyl (Mca) upon enzymatic cleavage by MMPs, which exhibits fluorescence with excitation and emission maxima at 328 nm and 420 nm, respectively.
