In addition, total gamma-H2AX activation was determined by flow cytometry. 2021-03-15 · View This Abstract Online; Flow cytometric detection of gamma-H2AX to evaluate DNA damage by low dose diagnostic irradiation. 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. 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).

The exposure to multiple CT scans causes more double strand breaks as compared to single scan. DNA damage can be studied by flow cytometric analysis of gamma-H2AX in human peripheral lymphocytes. assays for the sensitive measurement of g-H2AX, using both microscopy and flow cytometry (21–25). 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).

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).

All reagents required for this protocol may be efficiently purchased together in our Intracellular Flow Cytometry Kit (Methanol) #13593, or individually using the catalog numbers listed below. pubmed.ncbi.nlm.nih.gov 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.

H2AX (gH2AX) was performed by flow cytometry to assess DNA repair defects in a FI Ratio γ. H2AX. 60.00. 70.00. 0.00%. Avg Ped RR (N=8). 94.88%. 99.29%.

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. The compounds were classified as true genotoxicants, nongenotoxicants and false genotoxicants showing positive results in in vitro genotoxicity assays, but negative results in in vivo genotoxicity assays.

X Phosphorylation Assay Kit (Flow cytometry) is a cell based assay formatted for flow cytometric detection of levels of phosphorylated Histone H2A.X.; find  a signal for triggering DNA repair system so the γ-H2AX foci assay has potential use in flow cytometry is the indirect evidence of existence of DSBs. To confirm  11 Jun 2015 The study was performed by quantitative flow cytometry measurements, since the use of foci counting would result in reasonable accuracy only  The FCM-γ-H2AX assay has sufficient analytical sensitivity and precision to measure levels of DNA damage and DNA repair for clinical purposes.

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.

Validated in WB, IHC, ICC/IF and tested in Mouse, Human. Cited in 178 publication(s). 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.
