The neutralization titer for qPCR-MN was defined as the highest reciprocal serum dilution necessary to achieve a 90% inhibition of the qRT-PCR signal; this endpoint was found to be in agreement with ...

Within 50 days of symptom onset, serum samples were obtained at three to four different time points and analyzed for neutralizing antibodies (NAbs) using the pseudovirus neutralization assay.

Three monoclonal antibodies to pertussis toxin were characterized and used to investigate its role in immunity. Antibody affinity correlated with toxin neutralization in in vivo and in vitro assays ...

The serologic relatedness of six avian reovirus isolates ( CO8, S1133, 81-5, 2408, 1733, and UMI 203) was determined using a virus-neutralization (VN) test and an enzyme-linked immunosorbent assay ...
