Using immunofluorescence and imaging flow cytometry, foci were measured in untreated cells and at 0.5, 3, 5 and 24 hours post-irradiation. In all lymphoblastoid cells treated with 2 Gy gamma radiation, there was a predictable induction of DNA strand breaks, with a modest but significant retention of foci over 24 hours in irradiated cells treated with Olaparib (ANOVA P 0.05).

Med Hypotheses. 2018; 115:22-28 (ISSN: 1532-2777) Quantification of gamma-H2AX foci can be achieved by various methods such as Western blotting, flow cytometry, visual analysis and computational analysis with a fluorescence microscope. The best sensitivity is achieved by computer analysis. Using immunofluorescence and imaging flow cytometry, foci were measured in untreated cells and at 0.5, 3, 5 and 24 hours post-irradiation.

Flow Cytometry: gamma H2AX [p Ser139] Antibody [NB100-384] - Analysis of gamma-H2AX in EPE Treated Jurkat Cells. Cells were treated for 3 hrs in 5ug/ml etoposide, Here, measurements of γ-H2AX immunofluorescence by microscopy and flow cytometry were compared as rapid biodosimetric tools for whole and partial body exposures. Ex vivo uniformly X-irradiated blood lymphocytes from one donor were used to generate a universal biexponential calibration function for γ-H2AX foci/intensity yields per unit dose for time points up to 96 hours post exposure. The H2AX assay was done and 10,000 cells were analysed for gamma H2AX positivity in flowcytometer. Results Significant gamma-H2AX positivity was found in cases versus control, the most significant DNA damage amongst cases was observed in cases with multiple CT scans. The flow cytometry analysis of γH2AX was used in another study to confirm the genotoxic potential of selected compounds in HepG2 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. The purpose of the present study was to assess immediate DNA damage after exposure to low level of ionizing radiation by the flow cytometric method of gamma-H2AX. Here, measurements of γ-H2AX immunofluorescence by microscopy and flow cytometry were compared as rapid biodosimetric tools for whole and partial body exposures.

Multispectral imaging flow cytometry reveals distinct frequencies of gamma-H2AX foci induction in DNA double strand break repair defective human cell lines. Cytometry A. 2012;81: 130–7. pmid:22170789 . View Article PubMed/NCBI 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.

Analysis of g-H2AX by microscopy is still considered to be the most sensitive detection method and may discriminate between differential g-H2AX responses with respect to drug type and cell population makeup (7). However, the In contrast, flow cytometry allows simple detection of gamma-H2AX in a large number of cells .

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.
