FIG 2.

Anti-DBPII reactivity profiles. Antisera from the different immunization groups were evaluated in an ELISA by endpoint dilution for cross-reactivity with variant recombinant DBPII alleles. Antigen preparations (2 μg/ml) were allowed to adsorb to the wells of microtiter plates and then allowed to react with different dilutions of antiserum from individual mice. Each curve is a four-parameter logistic regression curve for antisera from each group (n = 14) against the different alleles, and error bars represent standard deviations.
