| Description: | The following example describes an assay that measured the ability of compounds to inhibit the binding of p53 to MDM2 using the AlphaScreen assay technology (PerkinElmer). The following protocol is an adaptation of the method described by H. R. Lawrence et al. (Bioorg. Med. Chem. Lett. 19 (2009) 3756-3759). Recombinant, truncated, human, N-terminal GST-MDM2 (aa 1-150) was obtained from GeneScript. Wild-type, full length human N-terminal 6-his p53 was purchased from SignalChem.Resulting in a final reaction volume of 24 μl PBS, 0.1% Tween-20, and 10% glycerol, 30 ng of MDM2 was added, followed by the addition of 10 of compound diluted in 100% DMSO that provided a final DMSO concentration of 4%. 30 ng of p53 was then added, mixed, and incubated at room temperature for 1 hour. Glutathione donor beads and Nickel acceptor beads (0.5 μg each; PerkinElmer) were added under subdued lighting conditions to a final reaction volume of 30 μl/well in a 96 well, volume Proxima plate. |
