FIG 1 .
ECIS easily distinguishes between wells of cells infected with different amounts of FHV-1. (A) CRFK cells were plated in ECIS wells, and impedance was monitored for 24 h at 16,000 Hz. Wells were then infected with FHV-1 at the MOIs indicated. The inset shows normalized impedance (Z′) values following FHV-1 infection. (B) Half-maximal Z′ (Z′50) values for impedance curves based on data from panel A. Different letters indicate significantly different Z′50 values, as determined by one-way ANOVA.
