Gamma H2AX (gammaH2AX) is the phosphorylated version of histone H2AX and is a marker for double-stranded breaks (DSBs) caused by DNA damage (1-4). H2AX is a variant of histone H2A, one of the histone core molecules forming the nucleosome, and is a vital component in repairing DNA damage (1-4).

DNA damage can be studied by flow cytometric analysis of gamma-H2AX in human peripheral lymphocytes. H2AX phosphorylation was analyzed by flow cytometry analysis as previously described 23, with small modifications. After treatment, 1 mL of 0.1% BSA‐PBS was added to the samples and PBMCs were pelleted (5 min at 2000 g) followed by fixation in 0.25% paraformaldehyde‐PBS (8 × 10 6 cells/mL), for 10 min on ice. 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 Measurement of c-H2AX by Flow Cytometry H2AX phosphorylation was analyzed by flow cyto-metry analysis as previously described (23), with small modifications. After treatment, 1 mL of 0.1% BSA-PBS was added to the samples and PBMCs were pelleted (5 min at 2000g) followed by fixation in 0.25% paraformaldehyde-PBS (8 3 106 cells/mL), for 10 min Antibody specific for gamma-H2AX is added and the positive cells are quantified for damage analysis, through flow cytometry.

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).

H2A.X Phosphorylation Assay Kit (Flow Cytometry) Overview: Phosphorylation of the histone variant H2A.X is a rapid and sensitive response to double strand DNA breaks. 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. Lastly, flow cytometry has been used to analyze γ-H2AX; however, flow cytometry methods are not readily integrated into HTS. Although each of the aforementioned methods of evaluating γ-H2AX is effective and has provided important information, there is still a need for an analytical high throughput assay that is capable of screening radiomodifying drugs across diverse cell lines and in vivo 2011-09-23 · Here, measurements of γ-H2AX immunofluorescence by microscopy and flow cytometry were compared as rapid biodosimetric tools for whole and partial body exposures.
