Abstract

A rapid single step assay suitable for the detection or quantification of enzymes, in particular, hydrolases, especially, aminopeptidases and esterases. The enzymatic reaction causes the cleavage of a metal ligand labelled hydrolase substrate. The cleaved ligand alters the electrochemiluminescence of bidentate aromatic heterocyclic nitrogen-containing ligand reagent. The change in electrochemiluminescence correlates to the presence of hydrolase activity present in the sample. The assay can be performed on an IGEN Origen.RTM. Analyzer.
