Flow cytometric analysis of HeLa cells, untreated (blue) or treated with UV (100mJ/cm2, 2 hr recovery; green) using Phospho-Histone H2A.X (Ser139) Antibody (solid lines) or concentration-matched Rabbit (DA1E) mAb IgG XP ® Isotype Control #3900 (dashed lines). 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). The detection of gamma-H2AX can potentially serve as a biomarker for transformation of normal tissue to premalignant and consequently to malignant tissues. gamma-H2AX has already been investigated in a variety of cancer types, including breast, lung, colon, cervix, and ovary cancers. 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. 2021-04-18 · Gamma-H2AX, phosphorylated KAP-1 and 53BP1 play an important role in the repair of heterochromatic radon-induced DNA double-strand breaks.

2010-02-04 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). 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). The results suggest gamma-H2AX is a useful adjunct in diagnosis of metastatic RCC when RCC-Ma is negative and in higher grade RCC, which are often a diagnostic challenge. A nuclear pattern of staining of gamma-H2AX has a comparable sensitivity with RCC-Ma, … 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) 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.

We H2AX is a member of the histone H2A family. 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 Anti-phospho-Histone H2A.X (Ser139) Antibody, clone JBW301 Anti-phospho-Histone H2A.X (Ser139), clone JBW301 is a well published Mouse Monoclonal Antibody validated in ChIP, ICC, IF, WB. This purified mAb is highly specific for phospho-Histone H2A.X (Ser139) also known as H2AXS139p. - Find MSDS or SDS, a COA, data sheets and more information. A number of ELISA Kits are available that target gammaH2ax, an alias of the protein, H2A histone family member X. The human protein, encoded by the gene H2AFX, is a member of the Histone H2A family.

Measurements of the DNA double-strand break response

Bonner’s team, collaborating with CCR colleague Andre Nussenzweig, Ph.D., established that H2AX is an acute sensor of a particularly harmful type of DNA damage called a Gamma-H2AX is involved in DNA double-strand break repair through both the non-homologous end-joining and homologous recombination. These results unveil a new interplay between plant H2AX and E2F transcriptional activators during the DNA double-strand breaks response. 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).

Laboratories around the world now use the gamma-H2AX assay developed by Bonner to study how cells sense and respond to double-strand breaks. The CCR team also used the gamma-H2AX assay to discover that cells’ genomic integrity may decline as we age in part because aging cells assemble damage repair machinery more slowly. 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.
