High-level ABL expression in BCR-ABL-transfected cell lines used in these studies.

Fluorescence intensity profiles of parental FDC-P1 cells (shaded) and its derivative clones FDbcr210A, E, and G (solid lines, panel A) and FDrv210C, F, and H (solid lines, panel B). Cells were permeabilized and stained with an anti-ABL antibody detected by a fluorescein-labeled secondary antibody.
