Abstract

A non-extraction high performance liquid chromatography assisted method for the measurement of angiotensin-converting enzyme in serum has been developed. Serum containing the enzyme was incubated with the synthetic substrate, furylacryloylphenylalanylglycylglycine at a concentration approaching 10 times the apparent Km, prior to injection onto a shielded hydrophobic reverse phase high performance liquid chromatography column. This allowed the product to be separated and measured directly without the need for a time consuming protein extraction step. The method is enzymatically sound and avoids the methodological problems associated with automated kinetic assays.
