| Description: | NCI-H358 cells expressing KRAS G12C mutant protein were cultured in RPMI 1640 medium (Gibco) containing 10% fetal bovine serum (Gibco). The NCI-H358 cells in culture medium were seeded in 96-well plates at a concentration of 40,000 cells/well and then put in a 37° C./5% CO2 cell incubator to incubate overnight. In the next day, the culture medium was removed and the compound diluted in assay medium (RPMI 1640, 0.1% FBS) was added in each well. After 2 hours incubation in a 37° C./5% CO2 cell incubator, the assay medium in 96-well plates was removed, then 50 μL of 1× blocking reagent-supplemented lysis buffer (Cisbio) was added and the plates were incubated at 25° C. for 45 min with shaking. 10 μL of cell lysates from the 96-well plates were transferred to a 384-well plate (Greiner) containing 2.5 μL/well HTRF pre-mixed antibodies (Cisbio 64AERPEH). Incubate 4 hours at 25° C. and then read HTRF signals on Tecan Spark multimode microplate reader. The data were analyzed using a 4-parameter logistic model to calculate IC50 values. |
