Absence of any significant NP-specific IgE responses to PSP.

<p>After NP-CGG immunization no changes in IgE antibody responses were observed at any time point (day 4, 7, 10, 14 or 21) to PSP NP- specific IgE titers were measured from two-fold serially diluted (1/5-1/20) serum samples by ELISA. Data are shown as the median from two independent experiments with 5–6 mice per group.
