Enzyme immunoassay of mumps virus in cell culture with peroxidase-labelled virus specific monoclonal antibodies and its application for determination of antibodies.
Mumps neutralizing monoclonal antibodies (MAs) were purified and labelled with horseradish peroxidase and used to detect virus-infected Vero cells, which were seeded as monolayers in wells of 96-well plates. This direct enzyme immunoassay (EIA) in cell culture proved to be a sensitive method for detection and titration of mumps virus and it may be useful for diagnostic purposes. The EIA is also suitable for the rapid determination of neutralizing antibodies. Neutralization of mumps virus by preincubation with either monoclonal or polyclonal antibodies was indicated by inhibition of the absorbance at 450 nm as measured with a multichannelled photometer. The EIA (duration 2 days) for determination of mumps neutralizing antibodies is an attractive alternative for the plaque reduction test (duration 6 days).
