| Description: | For the determination of AOC3 activity or compound inhibition potency, the compound inhibitors are dissolved in DMSO and adjusted to the respective assay concentration with reaction buffer (50 mM HEPES, 5 mM KCl, 2 mM CaCl2, 1.4 mM MgCl2, 120 mM NaCl, 0.001% (v/v) Tween 20, 100 μM TCEP, pH 7.4). An aliquot of 3 μL of the compound dilution is added to a 384 well plate (Optiplate, PS, flat bottom, white, PERKIN ELMER, #6007290) with a final DMSO concentration of 6.6%. Recombinant CHO cells, overexpressing the human (1500 cells/well), mouse (1000 cells/well) or rat (500 cells/well) AOC3 enzyme are diluted in reaction buffer and added in a volume of 15 μL to the wells. After incubation for 20 minutes at 37° C., 2 μL of MAO substrate (dissolved in DMSO at 16 mM, adjusted to assay concentration in reaction buffer to a final assay concentration of 20 μM) is added and further incubated for 60 minutes at 37° C. The turnover of the substrate is determined by the addition of 20 μL of the detection-mix which was generated by the addition of reconstitution buffer with esterase (PROMEGA, #V1402) to the luciferine detection reagent (PROMEGA, #V1402). After an incubation period of 20 minutes, the luminescent signal is measured with Envision 2104 Multilabel Reader (PERKIN ELMER). |
