Recommendations for Infection: Plate cells 18-24 hours prior to infection and infect when cultures are 80-90% confluent. Remove medium and inoculate with a small volume of virus (e.g. 1 mL per 25 cm2) diluted to provide an optimal MOI (e.g. 0.1 to 0.01). Adsorb 1-2 hours at 35°C in a humidified 5% CO2 atmosphere. End adsorption by adding virus growth medium.

Incubation: 2-3 days at 35°C in a humidified 5% CO2 atmosphere, until CPE is progressed through 75% of the monolayer.
