n-cbz-phe-arg-amc

N-CBZ-Phe-Arg-AMC (Z-FR-AMC) is a substrate for serine proteases, including cathepsins, kallikrein, and plasmin. The substrate exhibits absorption emission at 330 390 nm (weak fluorescence), while the end product (AMC) shows absorption emission at 342 441 nm (strong fluorescence).

N-CBZ-Phe-Arg-AMC TFA (Z-FR-AMC TFA) is a fluorescent substrate for serine proteases, which releases free AMC upon protease cleavage. Its excitation/emission wavelengths are 380/460 nm, and it can be used to assess the activity of trypsin, plasmin, and cathepsin.

N-CBZ-Phe-Arg-AMC hydrochloride (Z-Phe-Arg-Amc HCl) is a substrate for catS protease. CatS protease is an important member of the cysteine protease family and is a lysosomal protease. It is expressed in many inflammatory processes and autoimmune diseases and can be used to assess the activity of lysosomal proteases.
