Southern blots showing RT-PCR detection of IL-3, BCR–ABL, and actin transcripts in single CD34⁺CD71⁻CD45RA⁻, CD34⁺CD71⁺CD45RA⁺, and CD34⁻ cells from one of the CML patients with predominantly Ph⁺ LTC-IC (no. 10) (A) and one with predominantly Ph⁻ LTC-IC (no. 11) (B). The expected sizes, in bp, are indicated for each PCR product. Negative controls are the same as in Fig. 1.
