Expression of

DOK1 in CD34⁺ EPO-stimulated cells.CD34⁺ cells were grown in the presence of 1 U/mL EPO, and total RNA was purified from the cells collected on respective days 0-12. The RT-PCR products (top panel, DOK1; middle panel, PBGD; and lower panel, CD34) from each day were separated in 1.2% agarose gel. M indicates a 100-bp DNA ladder, and N indicates no DNA control.
