Detection of antigen-specific IgG in the serum of immunized mice.

<p>Post-immune serum (day 28) was used to determine the amount of total IgG specific for each recombinant antigens using ELISA as described in the text. Each symbol represents one mouse and the geometric mean is represented by a line. Dashed lines indicate the lower limit of detection (93 ng/ml). *<i>p</i><0.05; 1-tailed Wilcoxon Signed Rank Test.
