Assay Method Information

Assay Name:  Enzymatic Assay
Description:  The MAO enzymatic assay was performed according to the fluorometric method described by Matsumoto and colleagues (Matsumoto et al., Clin. Biochem. 1985, 18, 126-129) with the following modifications. Human recombinant MAO-A and MAO-B expressed in insect cells were used. For both assays, test compound and/or vehicle were preincubated with purified enzyme in phosphate buffer pH 7.4 for 15 minutes at 37° C. The reaction was initiated by addition of 50 μm kynuramine. Following a 60 minute incubation period, the reaction was terminated by the addition of 6 N NaOH. The amount of 4-hydroxyquinoline that formed was determined by spectrofluorimetrically at 325 nm/465 nm.
