Concentration-dependent induction of luciferase in BG1LucERβ clone 9 and the parent cell line BG1Luc4E2 by estrogen. Cells were incubated with E2 (24 h), lysed, and luciferase levels measured and analyzed as described in Materials and Methods. Luciferase activity is expressed as relative light units (RLUs) and values represent the mean ± SD of triplicate determinations after subtraction of the luciferase activity obtained in cells exposed to DMSO and are representative of more than 15 different replicate experiments.
