Bcr/Abl RNA expression in STI571-resistant Ba/F3.p210 cells.

Northern blotting was performed on mRNA extracted from nonresistant and STI571-resistant Ba/F3.p210 cells. (A) Northern blot using a cDNA probe from the C-terminus of c-Abl. (B) Northern blot using a cDNA probe from c-Bcr. See “Materials and methods” for details of each probe. Each Northern filter was stripped and re-probed with human G3PDH, as a control for loading.
