Neutralization Assay
Human sera from 100 healthy New Zealand donors were used to study the presence of antibodies neutralizing the mitogenic activity of recombinant SMEZ variants. The figures given are the percentage of inhibition compared with a reference test in which human serum was replaced by FCS. The table shows the results obtained with 20 selected sera. The remaining 80 sera all showed high neutralizing responses for the whole panel of variants.
