Figure 2.
Kinetics of the primary GC response. The percentage of GC B cells out of live lymphocytes was assessed by co-staining with anti-B220 and GL-7 antibodies. The data represent the average number and standard deviation from individual mice (n = 3–9). The background staining with these antibodies was determined from naive mice, and is indicated (along with SD) by the hatched area. *, **: Staining that is statistically different from background at P <0.001 and P <0.005, respectively, using the student's t test.
