From: Antiviral effect of copper chloride on feline calicivirus and synergy with ribavirin in vitro
The antiviral effect of different doses of copper chloride (20–200 μM) on F81 cells infected with FCV at 100 TCID50 . After incubation for 28 h at 37 °C in 5% CO2, the virus titre (a) and the relative RNA levels (b) of FCV were detected. c The IC50 of copper chloride for FCV was determined; * p < 0.0332; ** p < 0.0021; *** p < 0.0002; and **** p < 0.0001
