| Description: | B-RAF, RAFV600E, and C-RAF: Compounds at a concentration of 3 mM are serially diluted (e.g. 10 μl, 90 μl of 100% dimethyl sulfoxide (DMSO)) seven times in 96-well plates for a total of 8 dilution points. Each DMSO dilution is further diluted 1:100 in kinase buffer (e.g. 5 μl into 495 μl kinase buffer) containing 50 mM HEPES pH 7.5, 10 mM MgCl2, 1 mM EGTA, 0.01% Brij-35.Each well in a 96-well Optiplate (Perkin Elmer 6005569) contains 30 μl of final volume per sample, including 10 μl compound at 3× the desired concentration, providing 10 μM at the final maximum concentration, 10 μl of kinase/antibody mixture at 3× the desired concentration of RAF recombinant kinases and antibody providing 5 nM final concentration of B-RAFV600E kinase (Invitrogen PV3849) and 3 nM final concentration of C-RAF Y340D/Y341D kinase (Invitrogen PV3805) and 2 nM final concentration of Eu-anti-GST antibody (PV5594), and 10 μl of 3× the desired concentration of kinase tracer 178 (Invitrogen PV5593) providing final concentrations of 20 nM tracer for B-RAFV600E kinase and 6 nM tracer for C-RAF kinase. The plates are incubated for 5 hours at room temperature and read on an EnVision plate reader (Perkin Elmer). |
