VR-1469® is a TC-adapted item derived from virus passaged in eggs (ATCC® VR-95™).
Effect on Host
CPE, rounding, degeneration, sloughing
Recommended Host
MDCK cells (ATCC® CCL-34™)
Growth Conditions Temperature: 35°C
Recommendations for Infection: For best results, infection should be performed on an 80-90% confluent, 18-48 hour old cellular monolayer. Prepare dilution of virus in minimum amount of volume (e.g. 1 mL per 25 cm2), optimized for propagation (e.g. MOI 0.01-0.1 recommended). Wash monolayer two times with PBS or serum free medium prior to inoculation. Adsorb virus dilution for 1-2 hours at 35°C in a humidified 5% CO2 atmosphere, rocking every 20-30 minutes to redistribute inoculum. End adsorption by adding virus growth medium.
Incubation: 2-4 days at 35°C in a humidified 5% CO2 atmosphere, until CPE is progressed through 80% of the monolayer.
Effect on Host
CPE, rounding, degeneration, sloughing
