Variant histone H2A which replaces conventional H2A in a subset of nucleosomes. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling. Required for checkpoint-mediated arrest of cell cycle progression in response to low doses of ionizing radiation and for efficient repair of DNA double strand breaks (DSBs) specifically when modified by C-terminal phosphorylation. As part of the Histone H2A antibodies category, this reagent supports investigation of chromatin organization, histone H2A variants including H2A.Z, and epigenetic modification states.
The stated application concentrations are suggested starting points. Titration of the Histone H2AX antibody may be required due to differences in protocols and secondary/substrate sensitivity.
A portion of amino acids 115-143 from the human protein was used as the immunogen for the Histone H2AX antibody.
Aliquot the Histone H2AX antibody and store frozen at -20oC or colder. Avoid repeated freeze-thaw cycles.
