Figure 3.
Anti-sTn (A) and anti-KLH (B) IgG antibody titers of the day 0 (D0, before immunization), day 27, 31, and 38 sera from mice immunized with sTn-KLH in combination with PBS, 13+14, Alum, 1a, and 2a, respectively. Each column represents the mean antibody titer for a specific serum of three parallel experiments, and the error bar indicates SEM. ** p < 0.05, *** p < 0.01, and **** p < 0.001 show the statistically significant level for the difference between two compared groups.
