Figure 1. Expression of transcripts encoding leukemia antigens in cell lines, primary adult B-ALL patients and normal donors.

β-actin was used as a positive control for the ability of primers to amplify the cDNA. N was a no (cDNA) template control. Right hand side labels indicate expected product size and M indicates the location of the 1kB marker (HyperLadder I). RT-PCR data is representative of at least two independent experiments.
