Abstract

Norepinephrine, dopamine and serotonin concentrations were measured in mouse whole brain. Animals were killed either by decapitation or by exposure to 250 msec microwave irradiation which produces irreversible inactivation of brain enzymes. The biogenic amines were determined by mass fragmentometry, fluorometry and by a combination of high performance liquid chromatography and an electrochemical detector. No differences were found in the levels of these neurochemicals between the two methods of animal sacrifice. Therefore, rapid inactivation of brain enzymes is not necessary prior to analysis for catecholamines and serotonin in mouse whole brain.
