  1. NAI titres represent the mean IC50 values for each ferret antiserum (italics) against the indicated viruses that were determined from an ELLA performed in duplicate. Titres from PR8 reassortant viruses where the N1 sequence matches the N1 used to produce the ferret antisera are in bold. All ferret antisera were produced via intranasal inoculation with PR8 reassortant viruses carrying H6 with the indicated NA. Source data are provided in the source data file.
