| | Lanthanide Fluoro-Immunoassay |
| Description: | The c-Met kinase inhibitory activity was analyzed using dissociation enhanced lanthanide fluoro-immunoassay (DELFIA, Perkin Elmer), which is a kind of time-resolved fluorescence (TRF). 10 mL of the compound prepared in the present invention, as a test compound, was put in a Greiner 96-well V-shaped bottom plate, and a tyrosin kinase buffer (20 mL) mixed with a c-Met enzyme was added thereto, and then the enzyme and the test compound were stirred for 15 minutes, followed by culturing. An ATP solution (10 mL) was added thereto to proceed with a kinase reaction at room temperature for 30 minutes, and then a 50 mM ethylene diamine acetic acid solution (EDTA, 40 mL) was added to stop the reaction. After that, the reaction mixture was transferred to a plate coated with Streptavidin, followed by culturing under shaking. After 2 hours, the cultured material was washed three times with a PBS-T buffer (PBS 0.05% Tween 20). The europium-labeled anti-phosphotyrosine antibody was diluted to 1:2,500, and 100 mL of the diluent was added per well, followed by culturing under shaking. After 1 hour, the cultured material was washed three times with a PBS-T buffer (PBS 0.05% Tween 20). 100 mL of an enhancement solution was added, followed by shaking culturing for 5 minutes, and then the reaction material was read out within a wavelength range of 615/665 nm using a Wallac Envision 2103 device. |
