Assay Method Information

Assay Name:  c-Met In Vitro Kinase Assay
Description:  Optiplate-384 well plate (PerKinElmer), kinase buffer (50 mM Hepes pH7.5, 25 mM NaCl, 2 mM DTT, 0.01% Tween 20, 5 mM Mg2+, 0.5 mM Mn2+), c-Met kinase (1038-1346AA, prepared in-house), c-Met substrate (PerKinElmer, #TRF0127-M), Lance@Eu-W 1024-anti-phosphotyrosine (PT66), (PerKinElmer, #AD0068), ATP (Invitrogen), DMSO (Sigma, #34869), water (Millipore, model Milli-Q). A mixture of c-Met kinase (final concentration 12.5 nM) and test compound (final DMSO is 0.5%) is pre-incubated at 30° C. for 20 min. Then ATP (final concentration 2.5 uM) and kinase substrate (final concentration 50 nM) are added. The resulting mixture is kept at 30° C. for 1 hr, followed by addition of the c-Met antibody. After 1 hr, the plate is read at 615 nm and 665 nm. The ratio of absorption values at 665 nm and 615 nm is calculated and used for the data analysis as follows. This assay has a Minimum Significant Ratio (MSA) of 2-3.
