Part of the book series: Methods in Molecular Biology ((MIMB,volume 814))

Abstract

Protocols are described for measurement in primary cultures of astrocytes of unidirectional fluxes of glutamate (influx and efflux), glutamate metabolism to glutamine or CO2, glucose influx, glycolysis, pyruvate dehydrogenation, oxidative metabolism of glucose, pyruvate carboxylation, glycogen synthesis, and glycogenolysis. References are made to the in vivo situation, and the importance of using metabolically competent cultures is emphasized.
