The invention relates to a method for the enrichment, isolation and/or identification of cleavage products of at least one enzyme from a sample. According to the invention, an enzymatically inactive mutant of a protease is used as an affinity material, said mutant furthermore maintaining its specific substrate nature. At least one cleavage product of the protease of which the mutant is used, and at least one cleavage product of the enzyme of which the cleavage products are to be analyzed, comprise at least one structural similarity. |
