| Description: | EGFR (T790M/C797S/L858R) Kinase Enzyme System from Promega, Cat No. VA7126. ADP-Glo™ Kinase Assay from Promega, Cat No. V6930. The mutant EGFR kinase (50 ng in 2 μL) was pre-incubated with serially diluted compounds (1 μL). The test compounds were serially diluted 5-fold in DMSO starting at a concentration of 500 μM. The serially diluted compounds in DMSO were further diluted 20-fold in water to yield a top concentration of 25 μM in 5% DMSO. After pre-incubation, enzyme kinase reaction was initiated by the addition of 2 μL of 2.5× reaction buffer. The reaction buffer consisted on Buffer A as supplied by the kit, 50 μM DTT, 2.5 mM MnCl2, 40 μg Poly(Glu4,Tyr1) substrate and 1 μM ATP. The kinase enzyme reaction was done for 60 minutes at room temperature. Further, 5 μL of ADP-Glo was added and incubated at room temperature for 40 minutes followed the addition of 10 μL pf Kinase Detection Reagent and incubation at room temperature for 45 minutes. Chemiluminescence was read in GloMax Discover instrument. |
