Before revision:  In the case of a simple toggle-switch, the output of this approximation was almost indistinguishable from the theoretical distribution. Our approach was finally applied to a number of simple two-gene networks simulated in silico from the mechanistic model and satisfactorily recovered an accurate version of the original networks.
After revision:  In the case of a simple toggle-switch, and we show that it can indeed fit real single-cell data. As a first step toward inference, our approach was applied to a number of simple two-gene networks simulated in silico from the mechanistic model and satisfactorily recovered an accurate version of the original networks.
