| Description: | For the assay, a mixture of 1 mM L-methionine/1 mM ATP (2× final pre-stopped concentration) in assay buffer; MAT2A (2× final pre-stopped concentration) in Assay Buffer and Working Phosphate Sensor Mixture (1.5 uM Phosphate Sensor/30 mM EDTA in Assay Buffer, which is 3× final concentrations) were prepared. Test compounds or DMSO were added to the appropriate well suing D300e digital dispenser. 5 μl/well of Assay Buffer was added to the wells corresponding to the negative control and 5 μl/well of MAT2A was added to all the wells except for those corresponding to the negative control. After incubating the plate at room temperature for 15 minutes, 5 μl/well of the 1 mM L-methionine/1 mM ATP mixture was added to all wells. The plate was centrifuged at 1000 rpm for 1 minute and then incubated at room temperature for 1 hour. 5 μl of the Working Phosphate Sensor Mixture was added to all wells and the plate was centrifuged at 1000 rpm for 1 minute. The plate was read for fluorescence at 450 nm after exciting at 430 nm. |
