Different clones were seeded, cultured ON, and treated with TNF-α, LPS, or IL-1β. Cells were trypsinized and GFP expression was analyzed by flow cytometry. Data was normalized and EC50, detection limit, and linear range were calculated using nonlinear regression 3-parameter fit using GraphPad Prism. 95% confidence intervals are shown between brackets. ND: not determined.
