| | Kinase Assay for EGFR |
| Description: | The assay is performed in a Black 384-well plate (available from Corning). EGFR kinase (is diluted in TR-FRET Dilution Buffer (PV3189, InVitrogen) at concentration of 0.4 ug/ml as stock solution, and then 2-fold serial diluted. Addition of 1 mM ATP initiated the reaction, and the reaction is incubated for 111 reaction at room temperature. 10 μL of the Tb-antibody (from InVitrogen)+EDTA (from InVitrogen) solution prepared was added to each well of the assay plate and mix briefly, and incubated for 30 min. The signal is monitored by using M5 microplate reader (Ex=332 nm, Em=488 nm and 518 nm). Each compound is tested in duplicate wells. EGFR without compound is used as control. Staurosporine (available from Sigma) is used as positive control compound. Inhibition was calculated as percentage of the EGFR activity (without compound). Each compound in Examples 1 to 7 showed >50% inhibition at 100 nM. |
