EMSA of 32Dcl3Neo+ and 32Dcl3CDP/cut nuclear proteins bound to the DM2 LF silencer oligomers following G-CSF induction. (A) Double-stranded DM2 oligomers were [γ-32P]dATP–labeled and incubated with equal concentrations (15 μg) of nuclear extracts prepared from uninduced (lane 2) and G-CSF–induced day 2 (lane 3) and day 4 (lane 4) 32Dcl3Neo+ cells. Lanes 1 and 5, labeled DM2 oligomers without addition of any nuclear extracts. (B) [γ-32P]dATP–labeled DM2 oligomers were incubated with 15 μg/lane of nuclear extracts prepared from uninduced (lane 6), G-CSF–induced (day 2, lane 7), and G-CSF–induced (day 4, lane 8) 32Dcl3CDP/cut cells. Arrows in A and B represent the CDP/cut protein-DNA complex.
