WebDec 20, 2012 · The HAI assay is used extensively for evaluation of influenza vaccine efficacy and in epidemiological studies of influenza virus infection. Mechanistically, the assay capitalizes on the fact that HA glycoproteins on the surface of influenza virions bind and agglutinate erythrocytes. Webassays is the last fully agglutinated well within the series, and, for HAI assays, the transition well is last non-agglutinated well within the series. The sample in the transition well has been diluted by a specific factor, such as 1/128, and the sample’s titer value is the inverse of the dilution factor, or 128 in this example.
