Bistability thresholds.

The activation (red) and deactivation (blue) thresholds characterizing the bistable regime (green) are defined as the concentrations of FasL at which the steady-state active Fas concentration (black) switches discontinuously from one branch to the other (stable, solid line; unstable, dashed line).
