Assay Conditions: ChIP results obtained with the antibody directed against H3K64me3
ChIP assays were performed using human K562 cells, the antibody against H3K64me3 (Cat. No. 25260) and optimized PCR primer sets for qPCR. ChIP was performed on sheared chromatin from 1 million cells. A titration of the antibody consisting of 1, 2, 5, and 10 µg per ChIP experiment was analysed. IgG (2 µg/IP) was used as negative IP control. QPCR was performed with primers for the promoter of the active GAPDH and EIF4A2 genes, used as negative controls, and for the Sat2 and Sata satellite repeats, used as positive controls. Figure 1 shows the recovery, expressed as a % of input (the relative amount of immunoprecipitated DNA compared to input DNA after qPCR analysis).Determination of the antibody titer
To determine the titer, an ELISA was performed using a serial dilution of the antibody directed against H3K64me3 (Cat. No. 25260) in antigen coated wells. The antigen used was a peptide containing the histone modification of interest. By plotting the absorbance against the antibody dilution, the titer of the antibody was estimated to be 1:5,500.Cross reactivity tests using the antibody directed against H3K64me3
To check the specificity of the antibody against H3K64me3 (Cat. No. 25260) a Dot Blot was performed with peptides containing different modifications of histone H3 and H4 or the unmodified H3K64 sequence. One hundred to 0.2 pmol of peptide containing the respective histone modification were spotted on a membrane. The antibody was used at a dilution of 1:5,000. Figure 3 shows a high specificity of the antibody for the modification of interest.Western blot analysis using the antibody directed against H3K64me3
Western blot was performed on histone extracts (30 µg) from HeLa cells using the antibody against H3K64me3 (Cat. No. 25260). The antibody was diluted 1:100 in TBS-Tween containing 5% skimmed milk. The marker (in kDa) is shown on the left, the position of the protein is indicated on the right.
