TRAF 1 and TRAF2 protein expression in normal and neoplastic B cells.

(A) TRAF1 protein was analyzed in normal CD19⁺ B cells (lanes 1-3) and B-CLL samples (lanes 4-15). A quantity of 20 μg total protein was used per lane. Amido-black staining indicated similar amounts of protein being loaded per lane. (B) TRAF2 protein was analyzed in normal CD19⁺ B cells (lanes 1-3) and B-CLL samples (lanes 4-16). A quantity of 20 μg total protein was used per lane.
