A successive C-terminal amino acid truncation reaction of peptides and proteins with avapor generated from a low-concentrated perfluoric acid in acetic anhydride is presented. The reaction products were analyzed with matrix-assisted laser desorption/ionization-time of flight mass-spectrometry giving ...
