Cytopathic effects of encephalomyocalditis virus (ECMV) on baby hamster kidney cells (BSR)
The BSR host cells are seeded in a 96-well plate and allowed to reach 100% confluence in the wells. The host cells are then infected with ECMV and a mock virus at 1:10 titrations following the plate map shown below. After the incubation, the monolayer of cells is fixed and stained with crystal violet. As the virus concentration increase, the host cells are killed and reducing the monolayer in the wells. The Celigo automatically quantifies the percentage of host cells remaining in each well which, in this example, contain serial dilutions of ECMV.
The confluence % data can be plotted to produce viral titer curves and determine TCID50s
