摘要
Hydrogen peroxide generated from the enzymatic oxidation of choline was detected using a chemiluminescent acridinium-9-carboxamide. The dose-response for choline (0-50 mu M) 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 mu L) and analysis time (<5 s per well). (C) 2006 Elsevier Ltd. All rights reserved.
