Double isotopic method using dansyl chloride for the determination of GABA in rat C6 astrocytoma cell cultures


, : Double isotopic method using dansyl chloride for the determination of GABA in rat C6 astrocytoma cell cultures. Journal of Neuroscience Research 16(3): 561-566

Methods are described for the quantitative measurement of GABA in culture. The method can be adapted to any amino acid or dansyl-chloride-reactive species. The sensitivity and selectivity of the procedure result from the double isotopic design in which (14C)-labeled internal standard was added to the samples before reaction with (3M)-labeled dansyl chloride. Values obtained by ion-exchange amino acid analysis of cultures agree closely with the values obtained by the double isotopic method. This method is sensitive enough to measure GABA intracellularly and the condition medium.
