NF-κB response characteristics at different TNF-α doses. Error bars indicate the standard deviation from the median response time, and are indicative of the natural variation in single cell response. A Peak nuclear p65/dsRed localization intensity vs. TNF-α concentration. The median peak intensity (red squares) changes by only a factor of four with in response to four orders of magnitude change in TNF-α concentration. B The integrated area under the first peak vs. TNF concentration for a single experiment, showing that the total NF-κB nuclear activity in the first peak remains constant. C Response time vs. TNF-α concentration. The cells activate faster for higher concentrations. D Number of nuclear localization oscillations vs. TNF-α concentration.
