| Description: | COS-7 cells (ATCC, Manassas, Va.) were plated in 24 well plates in DME+5% csFBS without phenol red at 70,000 cells/well. Once the cells attached to the plates (typically after overnight incubation after plating), they were transfected in OPTIMEM medium (Life Technologies) using lipofectamine reagent (Life Technologies) with 0.25 μg GRE-LUC, 25 ng pCR3.1 GR, and 10 ng CMV-renilla LUC per well. Twenty-four hours after transfection, the cells were fed with DME+5% csFBS without phenol red (Fisher Scientific, Waltham, Mass.) and treated with the test compounds (1 pM to 10 μM dose range) in the presence of 0.1 nM dexamethasone (Sigma, St. Louis, Mo.). Sixteen to twenty-four hours after treatment, a luciferase assay was performed using the Dual Luciferase assay kit (Promega, Madison, Wis.). Firefly luciferase values were normalized to Renilla luciferase numbers. |
