I stained pancreatic cancer cells (Panc-1) for gamma-H2AX and got a large amount of foci in control cells (cells which have not undergone any genotoxic stress γH2AX as an assay for double-strand breaks. An assay for γH2AX generally reflects the presence of double-strand breaks in DNA, though the assay may indicate other minor phenomena as well.

Mix well. Pipette 392 μL of Assay Buffer into the 800 pM tube. Das Histon H2AX ist ein Protein aus der Gruppe der Histone, das im Zellkern aller Eukaryoten vorkommt. Es stabilisiert die Erbinformation und bildet zusammen mit den DNA-Molekülen Nukleosome und mit weiteren Proteinen Chromatin-Komplexe. Zusätzlich hat H2AX mehrere Aufgaben bei der DNA-Reparatur, der Instandhaltung der Chromosomen und im Zellzyklus.

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).

Gamma-H2AX assay is an immuno-fluorescence experiment that enables detecting the location and number of DNA double strand breaks (DSBs) in cells. Assuming that a single gamma-H2AX focus corresponds to a single DSB, one can convey the severity of cellular damage by the number of gamma-H2AX foci per cell (FPC) [1].

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.

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.

Here, we evaluate the minipig for its potential in γ-H2AX-based biodosimetry after exposure to ionizing radiation using both Cs137 and Co60 sources. γ-H2AX foci were enumerated in blood lymphocytes and normal dosimetry assays (Dicentric chromosome (Dic), Micro-Nuclei (MN), Premature Condensed Chromosome (PCC), Gamma-H2AX and Gene Expression), in case of large scale radiation accidents. For this purpose, all assays have been adapted to handle a large number of samples.

Semi-quantitative (2) Biologically active Clear. No (1) Detection method tissues. gamma-H2AX has already been investigated in a variety of cancer types, including breast, lung, colon, cervix, and ovary cancers. The prognostic value of gamma-H2AX is indicated in certain cancer types, such as breast or endometrial cancer, but further investigation is needed to establish gamma-H2AX as a prognostic marker. 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.

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. 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. Evaluation of the gamma-H2AX assay for radiation biodosimetry in a swine model.

2012-12-31 2018-06-01 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. The protein's cellular localization is indicated to be nuclear. Additional synonyms or past names for this protein may include: H2A.X, H2A/X, H2AX. 2017-02-03 hi azeez, i use software to count the gamma H2AX foci.

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 drug screening, basic research and

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). CONCLUSIONS: This inter-comparison exercise has demonstrated that following a recent acute radiation exposure, the gamma-H2AX assay could be a useful triage tool that can be successfully applied across a network of laboratories. PMID: 27686523 [Indexed for MEDLINE] Publication Types: Comparative Study; Evaluation Studies; Validation Studies; MeSH terms 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. 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.

The second gamma-H2AX assay inter-comparison exercise carried out in the framework of the European biodosimetry network (RENEB). Moquet J(1), Barnard S(1), Staynova A(2), Lindholm C(3), Monteiro Gil O(4), Martins V(4), Rößler U(5), Vral A(6), Vandevoorde C(6)(7), Wojewódzka M(8), Rothkamm K(1)(9). 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 ]. Following radiation exposure, histone H2AX is rapidly phosphorylated by ATM and/or DNA-PK kinases at or near the vicinity of DNA DSB sites to form γ-H2AX [ 14 ]. 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).
