VSFP sensing capacitance for slow membrane potential changes. (A)CVSFP as function of membrane voltage close to half activation for VSFP sensing charges with valences between 0.8 and 2 and an assumed membrane expression of 500 VSFP units/μm2. (B) CVSFP at half activation (membrane voltage equal to V1/2) versus density of VSFP membrane expression for sensing charge valences between 0.8 and 2. The capacitance was calculated from a generic two-state VSFP model in quasi-steady-state approximation (see text). The temperature is set to 37°C.
