Contract Services are also available. Phosphorylated on Ser-140 (to form gamma-H2AFX or H2AX139ph) in response to DNA double strand breaks (DSBs) generated by exogenous genotoxic agents and by stalled replication forks, and may also occur during meiotic recombination events and immunoglobulin class switching in lymphocytes. Anti-phospho-Histone H2A.X (Ser139), clone JBW301 is a well published Mouse Monoclonal Antibody validated in ChIP, ICC, IF, WB. This purified mAb is highly specific for phospho-Histone H2A.X (Ser139) also known as H2AXS139p. Flow cytometric analysis of HeLa cells, untreated (blue) or treated with UV (100mJ/cm2, 2 hr recovery; green) using Phospho-Histone H2A.X (Ser139) Antibody (solid lines) or concentration-matched Rabbit (DA1E) mAb IgG XP ® Isotype Control #3900 (dashed lines). Phosphorylated H2AX (gamma-H2AX) is essential to the efficient recognition and (or) repair of DNA double strand breaks (DSBs), and many molecules, often thousands, of H2AX become rapidly phosphorylated at the site of each nascent DSB. An antibody to gamma-H2AX reveals that this highly amplified process generates nuclear foci. 2019-09-27 Histone H2AX phosphorylation on a serine four residues from the carboxyl terminus (producing gammaH2AX) is a sensitive marker for DNA double-strand breaks (DSBs). DSBs may lead to cancer but, paradoxically, are also used to kill cancer cells.

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. 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. Rabbit polyclonal gamma H2A.X (phospho S139) antibody. Validated in WB, IHC, ICC/IF and tested in Mouse, Human.

Se hela listan på academic.oup.com 2017-02-03 · Phosphorylated H2AX (γ-H2AX) is a sensitive marker for DNA double-strand breaks (DSBs), but the variability of H2AX expression in different cell and tissue types makes it difficult to interpret the meaning of the γ-H2AX level. Furthermore, the assays commonly used for γ-H2AX detection utilize laborious and low-throughput microscopy-based methods. We describe here an ELISA assay that 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.

Gamma H2AX foci are always formed in case of DNA double strand breaks as a first step in its repair. As there is no repair without a previous damage I would not say that these foci represent H2A.X is required for checkpoint-mediated cell cycle arrest and DNA repair following double-stranded DNA breaks (1).

Here, we developed an image analysis system for the precise quantification of the gamma‐H2AX signal, which we used to monitor DNA damage in animals treated with known genotoxicants (EMS, ENU and doxorubicin). Phosphorylation of histone protein H2AX on serine 139 (gamma-H2AX) occurs at sites flanking DNA double-stranded breaks (DSBs) and can provide a measure of the number of DSBs within a cell.

Gingival fibroblaster motstår apoptos som svar på oxidativ

in a series of human biopsies, non-metastatic SCCs displayed a higher degree of chromosomal alterations and higher expression of the S phase regulator Cyclin E and the DNA damage signal gammaH2AX than the less aggressive, non-squamous, basal cell carcinomas. Gamma-H2AX hat sich als sensitiver Nachweis für DNA-Doppelstrangbrüche in der Wissenschaft etabliert, vor allem in der Strahlenbiologie. Die biologische Funktion von gH2AX ist zurzeit noch nicht völlig geklärt.

As a result of DSBs, H2AX becomes phosphorylated at serine-139 (p Ser139). Phosphorylation of the Ser-139 residue of the histone variant H2AX, forming γH2AX, is an early cellular response to the induction of DNA double-strand breaks. Detection of this phosphorylation On the contrary, gamma-H2AX foci are reduced to background levels 24 h post-irradiation with 200 mGy (60)Co gamma-rays. Conclusion: gamma-H2AX foci response and repair kinetics depend on irradiation conditions and radiation quality, possibly linked to Bystander response. H2A histone family member X (usually abbreviated as H2AX) is a type of histone protein from the H2A family encoded by the H2AFX gene. An important phosphorylated form is γH2AX (140S), which forms when double-strand breaks appear. The H2AX histone was first reported by West and Bonner in 1980, as a specific variant of the H2A histone family.

View specifications, prices, citations, reviews, and more. Laboratories around the world now use the gamma-H2AX assay developed by Bonner to study how cells sense and respond to double-strand breaks. The CCR team also used the gamma-H2AX assay to discover that cells’ genomic integrity may decline as we age in part because aging cells assemble damage repair machinery more slowly. 2016-03-31 Phosphorylated on Ser-140 (to form gamma-H2AX or H2AX139ph) in response to DNA double strand breaks (DSBs) generated by exogenous genotoxic agents and by stalled replication forks, and may also occur during meiotic recombination events and immunoglobulin class switching in lymphocytes.
