Half-life of GPI-specific plasma cells. Eight-week-old K/BxN and BxN mice (n = 2–5 for each time point) were fed BrdU (0.8 mg/mL) in the drinking water for the indicated amount of time. The percentage of BrdU⁺ cells (mean + SD) in each population defined as in Fig. 3 is plotted [GPI intracellular staining (G)]. Lymphocytes were excluded from the G^-CD138⁺ population by forward-scatter and side-scatter.
