| | Aurora B Kinase Test |
| Description: | Recombinant human Aurora B (amino acids 1-344, clone number DU1773, Molecular weight 40.2 kDa, University of Dundee) was expressed as a fusion protein with an N-terminal His tag. The test compounds were dissolved in 100% DMSO at a concentration of 10 mM and diluted in DMSO to a concentration of 5 mM. Serial Dilution is done in 1:10 steps in 100% DMSO. All further dilutions of the substances were carried out with test buffer (50 mM Hepes, pH 7.5, 10 mM MgCl2, 1 mM EGTA, 60 μM Ultra Pure ATP, 0.01% Brij35, 0.1% BSA, 5 mM 8-Glycerophosphate) until a concentration was reached which was 2.5 times above the final test concentration (final concentration of the compounds: 50 μM to 0.005 nM). 4 μl aliquots of these dilutions were transferred into a 384-well Optiplate (Perkin Elmer, #6007290). His-Aurora B was diluted to 125 nM in the test buffer and 4 μl of this dilution were used in the kinase test (final concentration of Aurora B=50 nM in a total volume of 10 μl). After 15 minutes incubation at room temperature 2 μl of 250 μM substrate ([LRRLSLGLRRLSLGLRRLSLGLRRLSLG]; University of Dundee) in test buffer were added to each well and the incubation was continued for a further 60 minutes at room temperature. |
