| Description: | BRAF and BRAF V600E: Inhibitory activities Inhibitory activities of compounds against BRAF, and BRAF V600E were measured by Invitrogen using Z′-LYTE Method as briefly described in the following. 4× Test compounds are dissolved in 1% DMSO. Kinase reaction mixture consists of 0.09-0.34 ng B-Raf (or 0.002-0.006 ng BRAF V600E), 1× inactive MAP2K1 (MEK1)/inactive MAPK1 (ERK2), and 2 μM Ser/Thr 03 in 50 mM HEPES pH 7.5, 0.01% BRIJ-35, 10 mM MgCl2, 1 mM EGTA. ATP solutions are diluted to a 4×ATP working concentration in Kinase Buffer (50 mM HEPES pH 7.5, 0.01% BRIJ-35, 10 mM MgCl2, 1 mM EGTA). Reaction started by 30-second shaking of mixture consisting of 2.5 μL 4× test compound, 2.5 μL 2× kinase reaction mixture and 2.5 μL 4×ATP Solution on Bar-coded Corning, low volume NBS, black 384-well plate (Corning Cat. #3676). Then the mixture was incubated for 60-minute at room temperature for the kinase reaction, followed by addition of 5 μL of a 1:1024 dilution of development reagent A and 30-second plate shake. The mixture was then incubated for another 60-minute at room temperature for development reaction. Fluorescence was read by plate reader. |
