Determination of 20-hydroxyeicosatetraenoic acid in microsomal incubates using high-performance liquid chromatography–mass spectrometry (HPLC–MS)
20-HETE is a potent, vasoconstrictive arachidonic acid metabolite with a limited number of published methods for quantitative assessment of microsomal formation rate. The purpose of this study was to evaluate the utility of HPLC–MS (negative ESI) for quantitation of rat microsomal 20-HETE enzyme kin...

Zusammenfassung: | 20-HETE is a potent, vasoconstrictive arachidonic acid metabolite with a limited number of published methods for quantitative assessment of microsomal formation rate. The purpose of this study was to evaluate the utility of HPLC–MS (negative ESI) for quantitation of rat microsomal 20-HETE enzyme kinetics. Calibration curves were linear over 0.75–16 ng on-column (
