Global comparison of neutralizing antibody binding levels of human plasma from 16 different donors against 16 different influenza T-B and B-T peptides, HIV gag peptide (HIV) and recombinant A/New Caledonia/20/99 protein (rHA NC), as measured by the inhibition of neutralization of A/New Caledonia/20/99 influenza virus. Number of viral plaques are given as mean of duplicates at a 1/80 dilution of plasma ± SEM. Background (number of plaques in peptide-free serum wells) was subtracted from each plaque count. Individual plaque counts (as presented in Figure 9) are shown by black circles, while mean plaque counts across all donors (average of all donors) are represented by a bar. All peptides had a p-value lower than 0.05 in a Mann Whitney test.
