Phospho-H2AX or γ-H2AX- is a marker of DNA double-stranded breaks and can therefore be used to monitor DNA repair after, for example, irradiation. In addition, positive staining for phospho-H2AX may indicate genomic instability and telomere dysfunction in tumour cells and tissues. Gamma H2A.X Staining Kit (ab242296) is based on the phosphorylation of the histone H2A.X at serine 139 in response to DNA damaging agents which cause double strand breaks in cells that are cultured in microtiter plates. The kit provides sufficient reagents for up to 100 stainings in 96- well plate. Gamma-H2AX immunofluorescence for the detection of tissue-specific genotoxicity in vivo. The phosphorylation of histone H2AX in Serine 139 (gamma-H2AX) marks regions of DNA double strand breaks and contributes to the recruitment of DNA repair factors to the site of DNA damage. Gamma-H2AX is used widely as DNA damage marker in vitro, but its use for genotoxicity assessment in vivo has no ….

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. H2A.X Phosphorylation Assay Kit (Flow Cytometry) 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.; find Sigma-Aldrich-17-344 MSDS, related peer-reviewed papers, technical documents, similar products & more at Sigma-Aldrich. By creating a dose-lymphocyte histogram (DLH), the gamma-H2AX staining method allows the estimation of the dose distribution after irradiation. One possible application of the present method could also be in radiation-protection for in-vivo dosimetry after accidental exposure to radiation. 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.

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.

In addition, positive staining for phospho-H2AX may indicate genomic instability and Gamma H2A.X Staining Kit (ab242296) is based on the phosphorylation of the histone H2A.X at 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, and the interpretation is easier and more reliable. RCC-Ma is 100% specific for RCC, but only when a membranous pattern of staining is interpreted as positive. PMID: 18528282 [Indexed for MEDLINE] Staining for gamma-H2AX was done by adding 5000–100 000 cells to 150–200 μl of Block 8 (PBS supplemented with 1 g/l BSA, 8% mouse serum (Sigma), 0.1 g/l RNase A type XII-A (Sigma), phosphatase inhibitors (10 mM NaF, 1 mM Na 2 MoO 4, 1 mM NaVO 3), 0.25 g/l sonicated herring-sperm DNA type XIV (Sigma), 0.1% Triton X100, 0.44 μg/l monoclonal anti-gamma-H2AX, FITC conjugate (Upstate biotechnology, 16-202A), 0.02% NaN 3).

Mammalian cells employ vigorous repair processes, including non-homologousend-joining(NHEJ),toreconnectbrokenchro-mosome ends, usually correctly, within a day or two after irradiation. Still the rejoining process is not perfect as has H2AX phosphorylation at Ser139 (formation of γ-H2AX) is an indicator of double-strand breaks in DNA (DSBs) after the action of different genotoxic stresses, including ionizing radiation, environmental agents, and chemotherapy drugs. The sites of DSBs can be visualized as focal sites of γ-H2AX using antibodies and immunofluorescence microscopy. 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.

Phosphorylation of the H2AX protein is an early step in the double strand break For our purposes, a double staining immunofluorescence was carried out with Damage Assessment: Gamma-H2AX Foci Counting and Cell Cycle Sorting. by. Blue staining indicates cell nuclei while pink staining indicates cytoplasm. (Other panels) γ-H2AX staining in tissues irradiated with 0, 0.2, 2.0, and 5.0 Gy and fixed By coupling γ-H2AX immunofluorescent labeling with either PI (flow cytometry) or DAPI (DIM) staining of the DNA, we were able to easily discern distinct cell cycle A, γ irradiation dosage dependent staining of γ-H2AX on T cells.
