The production of viral progeny was measured in RK‐13 cells using the Reed–Muench method as described previously (1 (link)). Briefly, the cells were grown to approximately 80%–90% confluence in 96-well cell plates (Corning, USA). The viral supernatants were serially diluted 10-fold, and 100 µL of each dilution was added to each well. After 1 h of virus adsorption, the cells were washed with PBS and incubated in 3% FBS DMEM. Five days post-infection, the TCID50 was calculated and analyzed using GraphPad 8.0.
