Dr1 is found at pol III-transcribed genes. HeLa cells were used for ChIP with Dr1 1162 (A) and Ab28185 (B) antibodies, together with the 1162 pre-immune (PI) serum and normal rabbit IgGs as negative controls. Brf1 and pol III antibodies were used as positive controls for pol III-transcribed genes and TBP as positive control for pol III- and pol II-transcribed genes. Input lanes show 10%, 2% and 0.4% of total input.
