According to the procedure, we have to;
Inoculate with 2-4 mL of EMCV suspension appropriately diluted in culture medium so that it contains about 2.5 × 10⁸ PFU/mL.
Each flask should contain 4-6 × 10⁶ L929 cells and therefore the MOI will be approximately 10 PFU/Cell.
Now I want to know, How the MOI had been calculated by these initial data that we have?
