| Description: | Assays were realized on 96-well plates, prepared with Biomek NKMC and Biomek 3000 from Beckman Coulter and read on Wallac Victor fluorimeter from Perkin-Elmer. Per well, 20 μL of farnesyl pyrophosphate (10 μM) was added to 180 μL of a solution containing 2 μL of varied concentrations of potential inhibitors (dissolved in DMSO) and 178 μL of a solution composed by 0.1 mL of partially purified recombinant yeast FTase (2.2 mg/ mL) and 7.0 mL of dansyl-GCVLS peptide (in the following buffer: 5.8 mM DTT, 6 mM MgCl2, 12 μM ZnCl2 and 0.09% (w/v) CHAPS, 53 mM Tris/HCl, pH 7.5). Then the fluorescence development was recorded for 15 min(0.7 second per well, 20 repeats) at 30°C with an excitation filter at 340 nm and an emission filter at 486 nm. Each measurement was realized twice as duplicate ortriplicate. |
