Characterization of viral growth kinetics in MDCK cells. Growth kinetics of the WT and MA viruses. MDCK cells were infected with the WT or MA virus at an MOI of 0.001 TCID50 per cell and treated with 1 mg/mL TPCK. At the indicated hpi, the virus titers in the supernatants were determined in MDCK cells. The reported values are the means and standard deviations of three independent experiments (**P < 0.01).
