Neutralization Assay for SARS-CoV-2 Infection: Plaque Reduction Neutralization Test

Neutralization assays are often used as part of research and diagnostics to detect neutralizing antibodies and to determine a possible protective antibody titer after infection or vaccination. Here we describe a conventional plaque reduction neutralization test (PRNT) to check the presence of antibodies against SARS-CoV-2 in patient samples (serum or plasma).
