Western blot - Human H2A.X (phospho S139) In-Cell ELISA Kit (IR) (AB131382)

Antibody specificity demonstrated by Western Blot Analysis : H2A.X (phospho S139) is phospho-specific. Jurkat cells were stimulated with UV light exposure to induce H2A.X (phospho S139) and then the UV treated lysate was treated with lambda protein phosphatase. Top panel : H2A.X (phospho S139) is induced by UV treatment and the western blot band is sensitive to phosphatase treatment. Lower panel : In contrast, total H2A.X (ab124781) levels are not sensitive to phosphatase treatment.

产品详情

The H2A.X (phospho S139) Human In-Cell ELISA Kit (IR) (ab131382) is designed to study the induction of DNA damage in response to various stimuli. A rabbit monoclonal antibody specific to H2A.X phospho S139 is used in this high-throughput duplexing plate-based assay. H2A.X (phospho S139) is a reliable readout for double-stranded DNA breaks.

Plates are available in our ICE (In-Cell ELISA) Support Pack (ab111542) which can be bought seperately.

In-Cell ELISA (ICE) technology is used to perform quantitative immunocytochemistry of cultured cells with a near-infrared fluorescent dye-labeled detector antibody. The technique generates quantitative data with specificity similar to western blotting, but with much greater quantitative precision and higher throughput due to the greater dynamic range and linearity of direct fluorescence detection and the ability to run up to 96 samples in parallel.

This method rapidly fixes the cells in situ, stabilizing the in vivo levels of proteins and their posttranslational modifications, and thus essentially eliminates changes during sample handling, such as preparation of protein extracts. Finally, the H2A.X (phospho S139) signal can be normalized to cell amount, measured by the provided Janus Green whole-cell stain, to further increase the assay precision.

This product is designed for LI-COR® Odyssey® or Aerius® infrared imaging systems.

The protein target H2A.X pSer139 also known as phospho-histone H2A.X and H2AX is a modified form of histone H2A.X which occurs when serine 139 becomes phosphorylated. This histone variant with a mass of approximately 15 kDa plays an important role in the DNA damage response. You can find H2A.X pSer139 in the chromatin of eukaryotic cells. It is especially abundant in tissues actively dividing like bone marrow and lymphoid tissues where it responds to DNA double-strand breaks by undertaking a structural change that signals the recruitment of repair proteins to the site of damage.

Biological function summary

H2A.X pSer139 serves as an indicator of DNA repair processes and contributes to maintaining genomic stability. When DNA damage occurs H2A.X rapidly phosphorylates and forms part of a complex including other repair proteins like MDC1 and 53BP1 marking regions for DNA repair machinery. By localizing with damaged DNA H2A.X pSer139 helps prevent genome instability by coordinating repair responses such as homologous recombination and non-homologous end joining.

Pathways

H2A.X pSer139 plays a significant role in the DNA damage response (DDR) and cell cycle checkpoint pathways. Within the ATM/ATR signaling pathway phosphorylation of H2A.X is an early step triggering cellular checkpoint controls and DNA repair. Proteins like ATM a kinase activated by DNA damage interact with H2A.X pSer139 phosphorylating it to initiate recruitment of repair complexes. Furthermore H2A.X pSer139 links with CHK2 a protein kinase in the DDR pathway helping regulate the cell cycle in response to DNA damage.

Alterations in H2A.X pSer139 function associate with cancer and neurodegenerative disorders. In many cancers defective DNA damage response often involving aberrations in H2A.X phosphorylation leads to genomic instability and tumor progression. In neurodegenerative diseases H2A.X pSer139 often coexists with proteins such as tau where DNA repair deficiencies contribute to neuronal damage. Understanding the regulation of H2A.X pSer139 offers insights into diseases and potential therapeutic targets.
