Description: | The phosphorylation activity on the peptide substrate of EGFR was investigated using LabChip (trademark) Systems (Caliper Life Sciences, Inc.). For the enzyme, EGFR [T790M/L858R] (Carna Biosciences, Inc.) was used. The test compound was added to a reaction liquid containing the enzyme protein to give 8 stages of final concentrations ranging from 300 nM to 0.1 nM, followed by incubation for 2 hours. Then, the substrate and the ATP solution were added thereto, followed by reaction for 1 hour. An ATP concentration of 1000 uM was used. A reaction liquid containing the enzyme protein but no test compound (in which the DMSO alone was added as a solvent at 0.4% in place of the test compound) was prepared, followed by reaction in the same manner with or without ATP addition. |
