Figure 1: Representative antibody responses to three peptide vaccines of EBV-gp350/220 in the rabbit (L-143) measured with ELISA. The vaccinated rabbit had sufficiently increased antibody titers against the 3 kinds of conjugated synthetic peptides (Pep-1, Pep-2, and Pep-3) of gp350/220, after three peptides conjugated with KLH (300400 g of each) were mixed with CFA and injected subcutaneously into the rabbit and additional KLHconjugated peptides (100200 g of each) mixed with IFA were injected at 2 and 5 weeks after the initial inoculation.
