There is 1 publication for this product available. The Rabbit Polyclonal anti-H2AFX antibody is suitable to detect H2AFX in samples from Human. It has been validated for WB and IF.
The antibody detects endogenous level of Histone H2A.X only when phosphorylated at serine 139.
Purification
The antibody was affinity-purified from rabbit antiserum by affinity-chromatography usingepitope-specific phosphopeptide. The antibody against non-phosphopeptide was removedby chromatography using non-phosphopeptide corresponding to the phosphorylation site.
Immunogen
Peptide sequence around phosphorylation site of pSer139 (Q-A-S (p) -Q-E) derived from Human Histone H2A.X. Antibodies were produced by immunizing rabbits with synthetic phosphopeptide and KLH conjugates.

Background
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.
