Figure 2. Dark noise benchmarking characteristics.

Figure 2

The benchmarking parameters D and S are defined as the ratio of the mean intensities (μ) and the standard deviations (σ) of the respective intensity distributions originating from the empty vector control (EV) and the autofluorescence (AF) of the parental strain. D is correlated to the accessible dynamic range and S is correlated to the sensitivity of the reporter system.
