Assay Method Information

Assay Name:  Inhibition Assay
Description:  When setting conditions for the measurement of the inhibitory effect of the compounds on FGFR2 kinase activity, FL-Peptide 22 (Caliper Life Sciences, Inc.) was used as a substrate. The purified recombinant human FGFR2 protein used in the test was purchased from Carna Biosciences, Inc. In the measurement of the inhibitory effect of the compounds, first, a test compound was gradually diluted with dimethylsulfoxide (DMSO) to a concentration that was 20 times higher than the final concentration. Next, the purified human FGFR2 protein, FL-Peptide 22 (final concentration: 1.5 .mu.M), magnesium chloride (final concentration: 5 mM), ATP (final concentration: 75 .mu.M), and the test compound DMSO solution (final concentration of DMSO: 5%) were added to a reaction buffer (15 mM Tris-HCl pH 7.5, 0.01% Tween-20, 2 mM DTT), and the mixture was incubated at 25.degree. C. for 120 minutes to perform a kinase reaction. EDTA (final concentration: 30 mM) diluted with a separation buffer.
