PANE1 transcript k is selectively expressed in resting CD19⁺ cells and B-CLL. (A) Relative expression levels of the CTL-7A7 mHAg-encoding PANE1 transcript k in different human tissues. Expression was determined by real-time quantitative RT-PCR as described in “Materials and methods.” The GAPDH gene was used as a standard to correct for RNA quantity and quality. (B-C) Relative expression levels of PANE1 transcripts c () and k (▪) in resting and activated fractions of human peripheral blood leukocytes (B), and in primary ALL and B-CLL samples (C).
