1. | ALA3706349 | B | Radioenzymatic Assay: The enzyme activity was assessed with a radioenzymatic assay using the substrate 14C-phenylethylamine (PEA) specific for MAO-B.The mitochondrial pellet (500 μg protein) was resuspended in 0.1 M phosphate buffer (pH 7.4). 200 μl of the suspension were added to a 50 μl solution of the test compound or buffer, and incubated for 30 min at 37° C. (preincubation) then the substrate (50 μl) was added. The incubation was carried out for 10 minutes at 37° C. (14C-PEA, 0.5 μM).The reaction was stopped by adding 0.2 ml of perchloric acid. After centrifugation, the deaminated metabolites were extracted with 3 ml of toluene and the radioactive organic phase containing the neutral and/or acidic metabolites formed as a result of MAO-B activity was measured by liquid scintillation spectrometry at 90% efficiency. | Rattus norvegicus | 7 | single protein format | BindingDB Database |
