Determination of BCR/ABL mRNA in LAMA84 and LAMA84R cells.
Samples containing 25 μg of total RNA per lane, extracted from LAMA84 and LAMA84R, were fractionated and analyzed by Northern blotting. A highly specific 40mer, corresponding to a portion of the b3-a2 junction sequence of BCR/ABL,14 was used as a probe and detected an 85-Kb transcript (upper panel). The same membrane was rehybridized with a murine β-actin probe (lower panel).
