Oligonucleotide pulldown analysis of C/EBPα and sumoylated-C/EBPα during ATRA-induction of MPRO cells. Nuclear extracts prepared from uninduced (0) and ATRA-induced (48h) MPRO cells were incubated with biotinylated C/EBP site (LF/C/EBP) oligomers from the LF promoter and OPD conducted as above. The blot was probed sequentially with anti-C/EBPα (lanes 3 and 4, top panel) and anti-SUMO-1 (lanes 3 and 4, bottom panel) antibodies. Input samples are represented in lanes 1 and 2 of the top (C/EBPα) and bottom (SUMO-1) panels.
