Abstract:
A rapid and specific high-performance liquid chromatographic assay for the quantitative determination of angiotensin-converting enzyme activity is described. Hippuryl-L-histidyl-L-leucine (Hip-His-Leu) is used as substrate and the released hippuric acid is measured. The procedure is accurate and precise and no extraction is required.
