Cell response distribution at the steady-state for different burst size values. Cell response distribution at the steady-state (100 h induction), at different autoinducer concentrations for the lux02 operon in the stochastic model for different burst size values: (A) bR=bI=20 (B) bR=bI=4 (C) bR=bI=0.01. The probability density of getting a particular GFP expression level is indicated by means of a density plot. The width of bistable region barely depends on the stochasticity levels, ≈7 nM. The black line stands for the concentration of GFP (normalized) as a function of in the deterministic model at the steady state.
