Blots were developed with Goat Anti-Rabbit IgG, (H+L), Peroxidase conjugated (ab97051) secondary antibody at 1/100,000 dilution for 1 hour at room temperature before imaging. The blot was developed on a BIO-RAD® ChemiDoc™ MP instrument using the ECL technique. Blocking/Diluting buffer and concentration : 5% NFDM/TBST Exposure Time : 37 seconds.

Peptide Array - Anti-Histone H2A.X antibody [EPR22820-23] - ChIP Grade - BSA and Azide free (AB256544)

All batches of ab229914 are 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, is available under the Product Protocol section.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab229914).

Target data

The protein expressed by the H2AX gene is a variant histone H2A that replaces conventional H2A in certain nucleosomes, which are responsible for wrapping and compacting DNA into chromatin. This compaction limits DNA accessibility to cellular machineries that require DNA as a template, placing histones at the center of transcription regulation, DNA repair, DNA replication, and chromosomal stability. DNA accessibility is controlled through a complex array of post-translational histone modifications, known as the histone code, and nucleosome remodeling. The H2AX protein is essential for the checkpoint-mediated arrest of cell cycle progression in response to low doses of ionizing radiation and for the efficient repair of DNA double strand breaks (DSBs), particularly when it undergoes C-terminal phosphorylation. This supplementary information is collated from multiple sources and compiled automatically.
