Why is so important plaque assay procedure?

The plaque assay procedure is crucial for quantifying viral particles in a sample by measuring the number of infectious units, which are represented by plaques formed on a monolayer of host cells. This method allows researchers to assess viral infectivity, study viral replication dynamics, and evaluate antiviral treatments. Additionally, plaque assays are essential for understanding viral pathogenesis and for vaccine development, as they provide insights into the virulence and behavior of viruses in controlled environments. Overall, this procedure is a foundational tool in virology that informs both basic research and clinical applications.
