Figure 2.
Proliferation of Tg and Tgmut B cells in response to anti-CD40 and anti-IgM stimulation. B cells from spleens of littermate control (▪), Tg line 28 (▦) , Tg line 23 (□), or Tgmut line 33 (▨ ) or were stimulated in vitro for 24 or 48 hours with anti-CD40 and anti-IgM. Incorporation of [3H] thymidine is shown with standard deviation (n = 4) for each bar.
