Fig. B1.

A typical experiment tracks single cells for $\approx 600$ min, which is long enough to distinguish the low-dose oscillatory regime (blue curve) from the exponentially damped oscillations that occur at slightly higher (black curve) and lower (green curve) levels of stimulation. The model here is the same as that depicted in Fig. 4 and has $\text{totalNFkB}=0.15\mathrm{\mu }\mathrm{M}$. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
