| Description: | SeedingCV-1 cells were seeded at a density of 2,000,000 cells in a T175 flask with DMEM+10% charcoal double-stripped FBS and incubated at 37° C. in 5% CO2 for 18 h (O/N).TransfectionAfter 18 h of incubation, the medium in the T175 flask was changed with fresh DMEM+10% charcoal super-stripped serum. In a polypropylene tube, 2500 μL OptiMEM (Life Technologies, Cat #31985-062) was combined with expression plasmids for hFXR, hRXR, TK-ECRE-luc and pCMX-YFP. The tube was then briefly vortexed and incubated at room temperature for 5 minutes. Transfection reagent (X-tremeGENE HP from Roche, Cat #06 366 236 001) was added to the OptiMEM/plasmid mixture vortexed and incubated at room temperature for 20 minutes. Following incubation, the transfection reagent/DNA mixture complex was added to cells in the T175 flask and the cells were incubated at 37° C. in 5% CO2 for 18 h (O/N).Test CompoundsCompounds were serially diluted in DMSO and added to transfected CV-1 cells. The cells were then incubated for 18 hrs. The next day cells were lysed and examined for luminescence. |
