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. 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 carboxy terminus of histone H2AX resulting in gamma-H2AX.

The H2A.X Phosphorylation Assay Kit (Flow cytometry) is a cell based assay formatted for flow cytometric detection of levels of phosphorylated Histone H2A.X. Cells are cultured in microplates, treated with agents that induce DNA damage or apoptosis, which stimulates H2A.X phosphorylation. Gamma-H2AX assay is an immuno-fluorescence experiment that enables detecting the location and number of DNA double strand breaks (DSBs) in cells.

2013-07-08 · DNA double-strand break repair kinetics in minipig blood lymphocytes and fibroblasts, based on the γ-H2AX assay, were similar to those observed in their human counterparts. To substantiate the similarity observed between the human and minipig we show that minipig fibroblast radiosensitivity was similar to that observed with human fibroblasts.

This new assay has been developed for anti-cancer Conversely, EMS appeared strongly positive in the comet assay but only mildly in the gamma‐H2AX immunofluorescence. These observations suggest that the two methods could complement each other for DNA damage analysis, where gamma‐H2AX staining allows the detection of … 2009-08-24 munocytofluorescence assay can be used to quantify ra-diation-induced changes in the phosphorylation status of the histone 2A.X (H2AX) (Redon et al.

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.

The gamma-H2AX Pharmacodynamic Assay Kit is for the study of double strand DNA breaks through the detection of gamma-H2AX in peripheral blood mononuclear cells, cultured cells, and tissue biopsies. Contract Services are also available. 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 , . PDF | On Jan 1, 2008, I.M. 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).

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.

The γ-H2AX assay has been applied for a variety of human tissues and cells. The best way to monitor the efficiency of cancer therapy would be to directly assay tumor biopsies, although a high variability of responses can occur due to cellular heterogeneity and vascularization. Over the past decade, the γ-H2AX assay has been applied to a variety of cell types and tissues to correlate γ-H2AX levels with DNA damage and repair [ 9, 10, 11, 12, 13 ].
