Figure 2

PCEP enhances IgA and IgG antigen-specific titers in lung washes of mice following intranasal and subcutaneous immunization. At the end of the 8 week experiment, lung washes from all the mice were collected and analyzed for X:31-specific IgA (A) and total IgG (B) titers by ELISA after receiving either PCEP+X:31 (closed bars) or X:31 alone (open bars) following IN, SC, oral, or IR immunization. Different letters indicate significant differences between groups that received PCEP+X:31, while asterisks indicate significant differences (i.e. adjuvant effect) between PCEP+X:31 compared to X:31 antigen alone (p < 0.05).
