Murine B-1 cells are radioresistant. a, Flow cytometry profiles of peritoneal B-1 (IgMhighIgDlow) and B-2 (IgMlowIgDhigh) cells at indicated time points postirradiation (5 Gy) (n = 6 mice). b, B cell recovery from PeC 48 h after indicated exposure (n = 3 per group). c, Kinetics of in vitro cell death determined by PI staining after 2 Gy exposure; representative of more than three experiments.
