FIG. 2.
Box plots of serum IgG antibody to GbpB peptide constructs QGQ and SYI. Serum IgG antibody activities against QGQ (left panel) and SYI (middle panel) peptide constructs and GbpB protein (right panel) were measured by ELISA. Sham-immunized and SYI-, QGQ-, and GbpB-immunized groups are indicated on the abscissae of each plot and represent the immune experience of 4 to 6 rats per group at 35 days after the first of two s.c. immunizations. Antibody reactivity is indicated on the ordinate as A405. Antibody levels are not directly comparable between panels. Group data indicated by box plots with a single asterisk are significantly different from data for the respective sham group (P < 0.001); double asterisks indicate a P value of 0.071.
