Western blot analysis showing
the inhibitory effect of TFO2 on the bcl-2 gene
expression at differing oligonucleotide concentrations (ODN amounts: 800,
400, 100, 10, 1 pmol). Plasmid pTRE-bcl2-tri was incubated with
different concentrations of specific TFO (TFO2) and SCR, and transfected
into HeLa cells that have been stably transfected with plasmid pTet-On.
Cells were lysed 24 h post-transfection and western blots were carried
out.
