title: Measurement of tyramine in human plasma, utilising ion-pair extraction and high-performance liquid chromatography with amperometric detection.
abstract: An assay for plasma tyramine has been developed which uses ion-pair extraction, reversed-phase ion-pair high-performance liquid chromatography and amperometric detection. Tritiated tyramine is used as the internal standard. The method can measure down to 0.5 ng/ml of tyramine in 1 ml of human plasma and is thus suitable for monoamine oxidase inhibitor studies involving oral dosing with tyramine.
