Gamma h2ax flow cytometry

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.

gamma-H2AX marks the site of damage and provides a nucleation site for the formation of damage response and repair complexes. Shigeaki Sunada, Hirokazu Hirakawa, Akira Fujimori, Mitsuru Uesaka, Ryuichi Okayasu; Oxygen Enhancement Ratio in Radiation-Induced Initial DSBs by an Optimized Flow Cytometry-based Gamma-H2AX Analysis in A549 Human Cancer Cells.

Validation of a flow cytometry-based detection of γ-H2AX, to measure DNA damage for clinical applications. Artikel i vetenskaplig tidskrift, refereegranskad.

Phosphorylated form of histone H2AX (γH2AX) is a generally accepted UCB MNC were irradiated with γ-rays (0, 5, 10, and 50 cGy) and then& Clone REA502 recognizes the human and mouse histone H2AX antigen phosphorylated at serine 139 (pS139). X, γ-H2AX, γH2AX Intracellular flow cytometry (3) applications for H2AX pS139 Antibody, anti-human/mouse, REAfinity™. Validated in WB, IHC, ICC, Flow Cyt and tested in Human.

Histone H2AX: Products. Histone H2AX is one of a number of core histone proteins. In the cellular response to genotoxic insults, ATM and related protein kinases phosphorylate the carboxyl-terminal tail of the H2AX protein (gamma-H2AX). gamma-H2AX marks the site of damage and provides a nucleation site for the formation of damage response and repair complexes.

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 epitope maps to a region surrounding phosphorylated serine 139 of human histone H2AX. Reactivity Human, Mouse, Rat, Canine Host Rabbit Isotype IgG Vial size 0.1 ml Concentration 1.0 mg

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. 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. To this end, we selected 14 well-known genotoxic compounds and compared them with 10 nongenotoxic chemicals, using CHO-9 cells because they are well characterized as to DNA repair and DDR. We quantified gamma-H2AX foci manually and automatically.
