ChIP results obtained with the antibody directed against AML1-ETO
ChIP assays were performed using Kasumi-1 cells, the antibody against AML1-ETO (Cat. # 25208) and optimized primer pairs for qPCR. Sheared chromatin from 1.25 million cells and 4 µl of antibody were used per ChIP experiment. QPCR was performed using primers specific for the FUT7, NFE2 and OGG1 genes. Figure 1 shows the occupancy, calculated as the ratio + control/background for which the promoter of the H2B gene was used.

ChIP-seq results obtained with the antibody directed against AML1-ETO
ChIP was performed as described above. The immunoprecipitated DNA of 6 ChIP assays was pooled and analyzed with an Illumina Genome Analyzer. Library preparation, cluster generation and sequencing were performed according to the manufacturer's instructions. The 32 bp tags were aligned to the human reference genome (hg18) using the ELAND algorithm. Figure 2 shows the results of the complete chromosome 3 and three genomic regions surrounding the OGG1, FUT7 and NFE2 genes, respectively. The position of the PCR amplicon is indicated with an arrow.

Determination of the antibody titer
To determine the titer of the antibody, an ELISA was performed using a serial dilution of the antibody directed against AML1-ETO (Cat. # 25208). The plates were coated with the peptides used for immunization of the rabbit. By plotting the absorbance against the antibody dilution (Figure 3), the titer of the antibody was estimated to be 1:32,750.

Western blot analysis using the antibody directed against AML1-ETO
Nuclear extracts of SKNO-1 cells (15 µg) were analyzed by Western blot using the antibody against AML1-ETO (Cat. # 25208) diluted 1:1,000 in TBS-Tween containing 5% skimmed milk. The marker (in kDa) is shown on the left, the position of the protein of interest is indicated on the right.
