Northern blot analysis of expression of the PU.1/Spi-1 gene (A) and the β-globin gene (B) in MEL-B8/3 cells after the differentiation induction. Total RNA was extracted from the cells at the indicated time after the addition of 1.5% DMSO to the culture, separated in a 1.0% agarose gel, transferred to a nylon membrane, and then hybridized with 32P-labeled probes.
