H2A histone family member X (usually abbreviated as H2AX) is a type of histone protein from cellular response to gamma radiation • spermatogenesis (a) Immunofluorescence staining shows that phosphorylated histone H2AX (γ- H2AX) is located in the nuclei of HCC cells (green) (original magnification ×100). 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.

Staining Against Phospho-H2AX (γ-H2AX) as a Marker for DNA Damage and Genomic Instability in Cancer Tissues and Cells. 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.

Flow cytometric analysis of HeLa cells, untreated (blue) or treated with UV (100mJ/cm2, 2 hr recovery; green) using Phospho-Histone H2A.X (Ser139) Antibody (solid lines) or concentration-matched Rabbit (DA1E) mAb IgG XP ® Isotype Control #3900 (dashed lines). In situ detection of DNA double strand breaks by immunofluorescent gamma-H2AX staining in mice exposed to multiwalled carbon nanotubes.

Measurements of the DNA double-strand break - GUPEA

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).
