GST mRNAs are expressed in human CFU-GM–, BFU-E–, and CFU-Meg–derived cells.

(A) RT-PCR analysis on mRNA expression for GSTM1 (lanes 1, 4, and 7), GSTT1 (lanes 2, 5, and 8) and β-actin (lanes 3, 6, and 9) in human CFU-GM–derived (lanes 1-3), CFU-Meg–derived (lanes 4-6), and BFU-E–derived (lanes 7-9) cells. (B) Negative RT-PCR control reactions (H₂0 in place of mRNA). Experiment was repeated 3 times with similar results.
