Antibody responses against the mixture of L1 + L2 peptides as an antigen in different groups: (A) total IgG, (B) IgG1, (C) IgG2a and (D) IgG2b; Mice sera were prepared from the whole blood samples of each group (n = 6) two weeks after the last immunization. All analyses were performed in duplicate for each sample shown as mean absorbance at 450 nm ± SD.
