Chromatin was prepared from HeLa cells. Cells were fixed with 1% formaldehyde for 10 minutes. ChIP was performed with 10⁷ cells and 4 µg of Anti-Histone H3 (tri methyl K4) antibody [EPR20551-225] - ChIP Grade. ChIP DNA was sequenced on the Illumina NovaSeq 6000 to a depth of 30 million reads.

Chromatin was prepared from Hela (human epithelial cel line from cervix adenocarcinoma) cells according to the Abcam X-ChIP protocol. Cells were fixed with formaldehyde for 10 min. The ChIP was performed with 25 μg of chromatin, 2 μg of ab213224(red), and 20 μl of Anti-rabbit IgG sepharose beads. 2 μg of Rabbit normal IgG was added to the beads control (grey). The immunoprecipitated DNA was quantified by real time PCR (Taqman approach). Primers and probes are located in the first kb of the transcribed region.

ab213224 was tested in Peptide array against 501 different modified and unmodified histone peptides; each peptide is printed on the array at six concentrations (each in triplicate).

Circle area represents affinity between the antibody and a peptide: all antigen-containing peptides are displayed as red circles, all other peptides as blue circles. The affinity is calculated as area under curve when antibody binding values are plotted against the corresponding peptide concentration. Each circle area is normalized to the peptide with the strongest affinity.

The complete dataset, including full list of all peptides and information on the position of each peptide in the diagram, can be downloaded here.
