FIG. 2.
Levels and compositions of AP-1-containing complexes in CSML0 and CSML100 cells. 32P-labeled double-stranded oligonucleotides containing collTRE (lanes 1 to 8 in panel A and lanes 1 to 10 in panel B) or an Oct-1 binding site (lanes 9 and 10 in panel A and lanes 11 and 12 in panel B) were incubated with CSML0 or CSML100 nuclear extracts as shown and analyzed by EMSA. Anti-Jun (A) and anti-Fos (B) antibodies were added, as indicated. The antibody-supershifted complexes are marked by arrows.
