Quick Overview for H2AFX antibody (pSer139) (ABIN362339)

Target: H2AFX (H2A Histone Family, Member X (H2AFX))

Reactivity: Human

Host: Rabbit

Clonality: Polyclonal

Conjugate: This H2AFX antibody is un-conjugated

Application: Western Blotting (WB), Immunofluorescence (IF)

Product Details anti-H2AFX Antibody

Binding Specificity: pSer139

Specificity: 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.

Isotype: IgG

Target Details for H2AFX

Target: H2AFX (H2A Histone Family, Member X (H2AFX))

Alternative Name: Histone H2A.X

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.
