<p>An agent for the detection of esterolytic or proteolytic enzymes containing (a) an amino acid ester or peptide ester of a phenol, as the chromogenic enzyme substrate, and (b) a substance, which accelerates the enzymatic cleavage of the aminoacid ester or peptide ester bond of component (a), which is a polyaminoacid with molecular weight of between 1,000 and 2,000,000, preferably a polyaminoacid which is built up from aminoacids of the general formula in which R represents hydrogen or an optionally branched alkyl, cycloalkyl or aralkyl radical which has 1 to 15 C atoms, preferably 1 to 9 C atoms, and is optionally substituted by 1 or 2 hydroxyl, mercapto, carboxyl, amino or guanido groups.</p> |
