FIG. 9.
Correlation of peptide avidity and antibody titer with neutralization titers among MAP-immune rabbits. A significant negative correlation between peptide IC50s and normalized TNA titers (A) and a significant positive correlation between antibody titers and TNA titers (B) were observed among all rabbits immunized with LND-containing MAPs. TNA titers from all MAP-immune rabbits were normalized to the control PA antiserum, as described in Materials and Methods. Correlations were determined using Spearman's ρ correlation. Note that two data points overlap along the x axis at an antibody titer of approximately 0 in panel B.
