What are recombinant viruses?
Recombinant viruses are genetically modified viruses used to study viral mechanisms and develop vaccines.
Why is generating high-quality viral stock important?
High-quality viral stock is crucial for accurate virological studies and experimental reproducibility.
What is a plaque assay?
A plaque assay is a method used to quantify the number of viral particles in a sample by counting the plaques formed in cell cultures.
How are BSR-T7/5 cells used in this study?
BSR-T7/5 cells are used for transfection to generate recombinant RSVs for further analysis.
What are inclusion bodies in the context of RSV?
Inclusion bodies are aggregates of viral proteins that form during viral replication and can be analyzed to study viral dynamics.
