The frequency of B220+PNAhigh GC B cells inWTand Neil1−/− mice. Mice were immunized with NP-CGG in alum and 2 weeks later their spleen cells were stained with PE-B220 and FITC-PNA. (A) Representative FACS profiles. (B) Percentages of B220+PNAhigh GC B cells in 10 pairs of WT and Neil1−/− mice (*p < 0.05, unpaired t-test).
