There is an increasing interest in new strategies to detect neurotransmitters released from nerve cells in real time for brain science, drug assessment, and so on. Previously we reported real-time monitoring of dopamine release from nerve model cells by enzyme-catalyzed luminescence measurement with tyramine oxidase and peroxidase. In the present study, the system was modified with glutamate oxidase instead of tyramine oxidase to detect L-glutamate sensitively ( approximately 10 nM) and rapidly with high temporal resolution (<1 s). We applied this modified method successfully to perform real-time monitoring of L-glutamate release from brain model cell (C6 glioma cell) using a luminescence plate reader upon stimulation with high concentration of KCl (>10 mM) or 5-hydroxytryptamine (>1 microM). The measurement solution was not toxic and therefore the L-glutamate release from the cell was measured by the second stimulation after exchanging the measurement solution. We conclude that the developed monitoring system is suitable for real-time detection of dynamic L-glutamate release from nerve cells in vitro and will be suitable for application in assessment of drugs acting on the nervous system.
