Independently reviewed in 26 review(s). Phosphorylated H2AX (also termed, gamma-H2AX) functions to recruit and localize DNA repair proteins or cell cycle checkpoint factors to the DNA-damaged sites. In this way, phosphorylated H2AX promotes DNA repair and maintains genomic stability and thus helps prevent oncogenic transformations. Shigeaki Sunada, Hirokazu Hirakawa, Akira Fujimori, Mitsuru Uesaka, and Ryuichi Okayasu "Oxygen Enhancement Ratio in Radiation-Induced Initial DSBs by an Optimized Flow Cytometry-based Gamma-H2AX Analysis in A549 Human Cancer Cells," Radiation Research 188(5), 671-674, (22 August 2017). Bourton et al., 2011 have recently demonstrated using nonimaging flow cytometry, that in peripheral blood lymphocytes (PBL) derived from radiotherapy patients that experienced severe acute and delayed normal tissue toxicity, there was a persistence of γ-H2AX foci following exposure to 2 Gy gamma radiation. Flow Cytometry, Methanol Permeabilization Protocol for Rabbit Antibodies A. Solutions and Reagents.

Several reports show that the level of gamma-H2AX as detected by flow cytometry correlates well with the number of DNA strand breaks, to the level of cell death and radiosensitivity (32–34). 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. This process is believed to play a key role in the repair of DNA damage. In this study, we established a flow cytometry (FCM) system for measuring radiation-induced phosphorylated histone H2AX (gammaH2AX) in cultured human T lymphocytes to evaluate individual radiation sensitivity in vitro. At present, flow cytometry is the most rapid method for detection of DSBs and cell viability. In this chapter, we provide our experience and methodological modification of flow cytometry protocol for the detection of γ-H2AX, a well-known marker of DSBs, in fixed mammalian fibroblasts.

Flow Cytometry: gamma H2AX [p Ser139] Antibody [NB100-384] - Analysis of gamma-H2AX in EPE Treated Jurkat Cells.

In this chapter, we provide our experience and methodological modification of flow cytometry protocol for the detection of γ-H2AX, a well-known marker of DSBs, in fixed mammalian fibroblasts. 2018-06-01 · Reportedly the gamma-H2AX can be quantified either by immunoflourescence or flow cytometry . Studies have suggested gamma H2AX quantification by immunoflourescence as a useful biomarker of human low level radiation exposure. In immunofluorescence method numbers of foci formed are individually counted by microscopic evaluation. This process is believed to play a key role in the repair of DNA damage. In this study, we established a flow cytometry (FCM) system for measuring radiation-induced phosphorylated histone H2AX (gammaH2AX) in cultured human T lymphocytes to evaluate individual radiation sensitivity in vitro.
