چکیده انگلیسی
A primary reason for poor characterization of microsomal transport to date is the limitations of the measurement techniques used. Radiodetection provides sufficient sensitivity, but it can be applied only when labeled analogue is available. In this article, we report the novel application of high-performance liquid chromatography and electrospray tandem mass spectrometry (LC-MS/MS) in “rapid filtration” transport assays. The method was developed using glucuronides, but it is adaptable to any compound that can be measured with LC-MS/MS. Because of the high sensitivity and accuracy of this detection technique, the substrates can be used at their physiological concentration in the experiments. The new methodology does not require radiolabeling, so it remarkably widens the range of possible substrates to investigate and allows simultaneous detection as well as monitoring of substrate stability during the experiments.
