A gamma-H2AX kit and antibody allows the assessment of DNA damage and DNA repair for ELISA based assays, immunohistochemistry or flow cytometry. In the detection of genomic damage, gamma-H2AX is especially important in research involving cancer treatment and therapy, and environmental biomonitoring.

Listed are ELISA Kits for the detection of H2AX, an alias name of H2A histone family member X. The human protein, encoded by the gene H2AFX, is 143 amino acid residues long and has a mass of 15,145 daltons.

Redon 2,* 1 Armed Forces Radiobiology Research Institute, Uniformed Services University, Bethesda, MD 20889-5603, USA; E-Mails: maria.moroni@usuhs.edu (M.M.); Gamma-H2AX foci detection is the standard method to quantify DNA double-strand break (DSB) induction and repair. In this study, we investigated the induction and decay of γ-H2AX foci of different tumor cell lines and fibroblasts with known mutations in DNA damage repair genes, including ATM, LigIV, DNA-PKcs, Rad51 and Rad54. A radiation dose of 2.4 Gy was used for either an acute single high γ-H2AX Standard - The kit contains 20 μL of γ-H2AX Standard at a concentration of 1 μM.

Abingdon, UK & Lake Forest CA, USA — AMSBIO announces the first commercially available gamma H2AX Pharmacodynamic assay kit for the study of double strand DNA breaks through the detection of gamma H2AX – a phosphorylated histone historically proven as a highly specific and sensitive molecular marker for double strand DNA damage detection. This new assay has been developed for anti-cancer

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.

2012-12-31 · The γ-H2AX assay has also been used to monitor formation and persistence of DNA damage and cytotoxicity in human cancer cells produced by another Auger emitter, 111 In, that has been delivered to cell nuclei by pharmaceuticals that target human epidermal growth factor receptor (EGFR)-positive cancers and HER2/neu-amplified breast cancers , .

Rakiman and others published γ-H2AX assay: a technique to quantify DNA double strand breaks | Find, read and cite all the research you need on ResearchGate Thus, with γH2AX we have a bio-indicator on hand for critical DNA lesions and severe genomic replication stress. Hence, the γH2AX assay is not an assay for detecting any type of DNA damage, but for biologically relevant and severe DNA damage (including DNA interstrand crosslinks that give rise to DSBs; Nikolova et al., 2012). Phosphorylated H2AX (gamma-H2AX) is essential to the efficient recognition and (or) repair of DNA double strand breaks (DSBs), and many molecules, often thousands, of H2AX become rapidly phosphorylated at the site of each nascent DSB. An antibody to gamma-H2AX reveals that this highly amplified process generates nuclear foci. 2017-02-03 · Phosphorylated H2AX (γ-H2AX) is a sensitive marker for DNA double-strand breaks (DSBs), but the variability of H2AX expression in different cell and tissue types makes it difficult to interpret the meaning of the γ-H2AX level. Furthermore, the assays commonly used for γ-H2AX detection utilize laborious and low-throughput microscopy-based methods. 2010-02-04 · Gamma-H2AX in recognition and signaling of DNA double-strand breaks in the context of chromatin.

Tested in Western Blot (WB), Immunofluorescence (IF), Immunocytochemistry (ICC), ELISA (ELISA) and Luminex (LUM) applications. This antibody reacts with All, Human, Mouse, Rat samples. Supplied as 100 µg purified antibody (1 mg/mL). We quantified gamma-H2AX foci manually and automatically. In addition, total gamma-H2AX activation was determined by flow cytometry. For all chemicals the cytotoxic dose response was assayed by a metabolic cytotoxicity assay. This modification, called gamma-H2AX (phospho-Ser139), triggers cell cycle arrest and DNA damage response repair, which makes this assay particularly appropriate for studying genome stability, cell cycle, DNA repair, and more broadly as a biomarker for cancer and for aging process investigations.

Conversely, EMS appeared strongly positive in the comet assay but only mildly in the gamma‐H2AX immunofluorescence.
