実験手順

The whole brains of mice of ddY-strain were homogenized and the resulting brain homogenate was diluted with the same volume of a buffere solution (comprising 50 mM Tris-HCl (pH 8.6, 1.5 mM EDTA.2Na); 0.5 mM Pridoxal-5-Phosphate; 1 mM Nialamide; and 0.85 mM L-ascorbic acid), and the mixture was centrifuged at 10,000 g to give a supernatant liquid containing the brain enzymes. To this supernatant liquid (500 μl) was added a solution containing 4.5 mM of a substrate selected from L-threo-adrenalinecarboxylic acid, L-threo-DOPS and L-DOPA. The mixture obtained (pH ca. 8, 1.0 ml) was incubated for 30 minutes at 37° C., followed by quantitative determination of adrenaline, noradrenaline or dopamine formed as the reaction product catecholamine.
