H2AX is a variant of histone H2A, one of the histone core molecules forming the nucleosome, and is a vital component in repairing DNA damage (1-4). 2007-02-06 Histone H2A.X (H2AX) is a member of the histone H2A family which is one of the four core histones making up the nucleosome core particle. In eukaryotes, DNA double strand breaks (DSBs) have been shown to trigger the phosphorylation of serine 139 at the … 2019-09-27 Anti-Gamma H2AX (phospho-Ser139) antibody, Rabbit monoclonal recombinant, expressed in HEK 293 cells, clone RM224, purified immunoglobulin Synonym: H2AX Ser139 p, Histone H2AX (phospho ser139) 2013-11-01 2013-11-29 2019-09-25 Gamma‐H2AX is used widely as DNA damage marker in vitro, but its use for genotoxicity assessment in vivo has not been extensively investigated. Here, we developed an image analysis system for the precise quantification of the gamma‐H2AX signal, which we used to monitor DNA damage in animals treated with known genotoxicants (EMS, ENU and doxorubicin). 2018-06-01 gamma-H2AX (gH2AX) is the phosphorylated form of histone H2AX and can function as a sensitive marker for double-strand breaks (DSBs), which signifies genomic instability and can potentially contribute to cancer initiation and progression. In this way, monitoring the formation of gH2AX can potentially be a sensitive means of cancer Immunocytochemistry/ Immunofluorescence - Anti-gamma H2A.X (phospho S139) antibody (ab11174) This image is courtesy of an anonymous Abreview.

Gamma h2ax

2016-03-31 Phosphorylated on Ser-140 (to form gamma-H2AX or H2AX139ph) in response to DNA double strand breaks (DSBs) generated by exogenous genotoxic agents and by stalled replication forks, and may also occur during meiotic recombination events and immunoglobulin class switching in lymphocytes. Gamma H2AX foci are always formed in case of DNA double strand breaks as a first step in its repair. As there is no repair without a previous damage I would not say that these foci represent gamma-h2ax-phospho-s139-antibody-ep8542y-ab81299.pdf.

The four core histones involved in the formation of the nucleosome structure of compacted chromatin are H2A, H2B, H3, and H4. H2AX may function to facilitate DNA repair, and recent studies have shown that H2AX is required for the maintenance of genomic stability. Gamma H2AX is the phosphorylated form of H2AX that results in response to DNA damage. Gamma H2AX (gammaH2AX) is the phosphorylated version of histone H2AX and is a marker for double-stranded breaks (DSBs) caused by DNA damage (1-4). This gamma-H2AX-based assay may be useful for biodosimetry for triage to distinguish among individuals who have received negligible doses from those with significantly exposures.

Tested in Western Blot (WB), Immunocytochemistry (ICC/IF) and Immunohistochemistry (IHC) applications. This antibody reacts with Human, Mouse samples. Supplied as 100 µL purified antibody (1 mg/mL). Phosphorylation of histone protein H2AX on serine 139 (gamma-H2AX) occurs at sites flanking DNA double-stranded breaks (DSBs) and can provide a measure of the number of DSBs within a cell. We H2AX is a member of the histone H2A family.

Apart from the exogeneous agents (radiation and Jan 20, 2016 Gamma-H2AX foci detection is the standard method to quantify DNA double- strand break (DSB) induction and repair. In this study, we Monoclonal Antibody for studying H2AX (Ser139) phosphate in the Chromatin Regulation / Epigenetics research area. A well-known histone modification induced by DNA damage is the phosphorylation of the histone variant H2AX into γ-H2AX in a Mbp large region around DSB. γ- We studied the spatial and temporal distributions of foci of the phosphorylated form of the histone protein H2AX (gamma-H2AX), which is known to be activated The compact, fully automatic Gamma 450 processes crimps and seals on both sides and takes up minimum space.
