Effect of Nlac PorB on induction of OVA-specific IgG subclasses. OVA-specific IgG1, IgG2a, IgG2b and IgG3 titers were measured by ELISA in the sera of immunized mice. The results represent the mean of triplicate wells ± standard deviation and are expressed as O.D.405. Significant differences (p=<0.05) with the OVA group were calculated by Mann Withney test and are indicated by (*) for Nlac PorB and (**) for alum.
