This video demonstrates the viral inactivation assay, showcasing the evaluation of the impact of antiviral agents on viral particles.
Protocol
1. Viral Inactivation Assay Note: Examples of incubation period and viral dose for various viruses are listed in Figure 1A. Higher concentrations of the virus can also be tested by increasing the MOI/PFU. Seed Huh-7.5 cells in a 96-well plate (1 × 104 cells per well) and incubate at 37 °C in a 5% CO2 incubator O/N to obtain a monolayer. Incubate the test compounds or controls (final concentrations are: CHLA…
Representative Results
Figure 1. Inactivation of viral infections by the test compounds CHLA and PUG. Different viruses were treated with the test compounds for a long period (incubated for 1.5 – 3 hr before titration; light gray bars) or short period (immediately diluted; dark gray bars) at 37 °C before a dilution to sub-therapeutic concentration and subsequent analysis of infection on the respective host c…
