Table 4 NASPA titers of type B vaccine viruses

From: Influenza neuraminidase active site proximity assay for rapid profiling of inhibitory antibodies and antigenic drift

  1. NASPA titers for each virus were generated using the indicated ferret antisera (italics) and correspond to the highest dilution factor above the control mean + 3 SD. Titers for NAs matching the antisera are bold.
  2. Antigenically related and distinct NAs are highlighted in light blue and purple, respectively.
