Integrated Gen5™ Microplate Reader and Imager Software controls Cytation 5, and also automates image capture, analysis and processing. Methods. Gamma H2AX Assay Performance Cultured U251 cells were treated with The DNA double-strand break (DSB) is the primary lethal lesion after therapeutic radiation. Thus, the development of assays to detect and to quantitate these lesions could have broad preclinical and clinical impact.

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. There is a paucity of large animal models to study both the extent and the health risk of ionizing radiation exposure in humans. One promising candidate for such a model is the minipig. Here, we evaluate the minipig for its potential in γ-H2AX-based biodosimetry after exposure to ionizing radiation using both Cs137 and Co60 sources.

This new assay has been developed for anti-cancer drug screening, basic research and 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.}, author = {Moquet, Jayne and Barnard, Stephen and Staynova, Albena and Lindholm, Carita and Monteiro Gil, Octávia and Martins, Vanda and Rößler, Ute and Vral, Anne 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.

Although it is commonly accepted that a γ-H2AX focus indicates the presence of a double strand break (DSB), while foci disappearance is associated with the repair of the DNA damage, the exact relationship between the number of foci and the number of DSBs is still a matter of debate [ 12 - 14 ]. The γ-H2AX assay has been applied for a variety of human tissues and cells.

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.

2010; Ivey et al. 2009). 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.

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.

In the cellular response to genotoxic insults, ATM and related protein kinases phosphorylate the carboxyl-terminal tail of the H2AX protein (gamma-H2AX). gamma-H2AX marks the site of damage and provides a nucleation site for the formation of damage response and repair complexes. 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. 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.
