(A) Development of anti-BCL1 reactivity in BALB/c and B10.D2. Values are taken from a representative experiment from three separate experiments and represent the mean ± SD of triplicate measurements. (B) Proliferation of B10.D2 T cells against BCL1 and BALB/c splenocytes. Splenic T cells from BCL1-inoculated B10.D2 mice were isolated and cocultured with irradiated BCL1 (8,000 rads) or BALB/c splenocytes (3,000 rads).
