FIG 3.

Quantitative analysis of anti-DBPII antiserum binding specificity. The binding specificity of antiserum from each immunization group was compared against that of recombinant Sal1, 7.18, P, and DEKnull by ELISA. Antibody titers were calculated as the serum dilution required to achieve 1.5 EU. Each bar represents the titer for each antiserum against a specific recombinant DBPII allele, and error bars indicate standard deviations. Asterisks indicate significant differences in antibody titers between the two groups.
