Any real-time PCR assay for SARS-CoV-2 RNA may be used as a read-out for Ct values to determine the viral weight of the assay. a 50% tissue culture infective dose (TCID50) of Vero cells. For the microneutralization assay, 19 serum samples, with positive IgG titers against Spike Receptor-Binding Domain name (RBD) were tested. After 24 hours, infected cells were inspected for the presence of a cytopathic effect, lysed and RNA RT-PCR conducted for SARS-CoV-2. PCR target Ct values were used to determine percent neutralization/inhibition of SARS-CoV-2. == Results == Out of 19 samples, 13 samples gave 100% neutralization at all…
