Figure 8.
ELISA results of overall total (A) and total IgG antibodies (B) in days 21, 28, and 35 antisera pooled from mice immunized with GM2-MPLA conjugate 2 or GM2-KLH conjugate 3, respectively. The average of antibody titers from three parallel experiments for each pooled antiserum is shown, and the error bar represents the standard deviation (SD). *The difference between the results of two conjugates is statistically significant (P < 0.05).
