Assay Method Information

Assay Name:  MAO Enzyme Inhibition Assay
Description:  The effects of the test compounds on hMAO isoform enzymatic activity were evaluated by measuring their effects on the production of hydrogen peroxide (and therefore, of resorufin) from p-tyramine, using the Amplex Red MAO assay kit (Molecular Probes, Eugene, Oregon, USA) and microsomal MAO isoforms prepared from insect cells infected with recombinant baculovirus containing cDNA inserts for human MAO-A or MAO-B. The production of H2O2 was quantified in a multidetection microplate fluorescence reader (FLX800, Bio-Tek Instruments, Inc., Winooski, VT) based on the fluorescence generated (excitation, 545 nm; emission, 590 nm) over a 15 min period, in which the fluorescence increased linearly.
