Rapid high-throughput detection of peroxide with an acridinium-9-carboxamide: A homogeneous chemiluminescent assay for plasma choline

Hydrogen peroxide generated from the enzymatic oxidation of choline was detected using a chemiluminescent acridinium-9-carboxamide. The dose–response for choline (0–50 μM) was established in buffer and was applicable to the quantification of choline in human plasma. This homogeneous assay was performed in a 96-well microplate format and required minimal sample volume (1 μL) and analysis time (<5 s per well).
