          Product Specific Information

          MA1-2022 was used in IHC to successfully detect H2A.X pSer140 in postnatal mouse lung section.

          MA1-2022 detects human and mouse phosphorylated H2AX.

          MA1-2022 has been used successfully in Western blot, immunofluorescence, and ELISA procedures. By Western blot this antibody detects ~17 kDa protein representing phosphorylated H2AX in gamma irradiated HeLa cell lysate. In immunofluorescence procedures, MA1-2022 recognizes phosphorylated H2AX in gamma irradiated HeLa cells. ELISA of phosphorylated H2AX can also be performed using MA1-2022. MA1-2022 was used in IHC to successfully detect H2A.X pSer140 in postnatal mouse lung section.

          The MA1-2022 immunogen is a synthetic peptide sequence surrounding phosphorylated Ser140. Some references call Ser140, by the name Ser139.

          This antibody was orginally validated as part of a Thermo Scientific Cellomics High Content Screening Kit. The antibody sold separately may have slightly different performance and may need to be further optimized for the best results.

          Target Information

          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. The phosphorylation of H2AX can be detected by Western blotting or immunofluorescence, revealing the frequency of DSBs. The phosphatidylinositol 3-kinases have been implicated in H2AX phosphorylation, but it is unclear if ATM is the primary H2AX kinase or if other members of the family such as DNA-PK and ATR contribute in a similar manner. Structurally, H2A.x contains 143 amino acid residues. Histone H2A.X is considered a basal histone, being synthesized in G1 as well as in S-phase, and its mRNA contains polyA addition motifs and a polyA tail along with the conserved stem-loop and U7 binding sequences involved in the processing and stability of replication type histone mRNAs. There are two forms of Histone H2A.X mRNA, one about 1600 bases long and contains polyA; the other about 575 bases long, lacking polyA. The short form behaves as a replication type histone mRNA, while the longer behaves as a basal type histone mRNA. Histone H2A.X maps to the 11q23.2-q23.3 region of the human chromosome. Histone H2A.x contributes to histone-formation and therefore the structure of DNA. Histone H2A variant H2A.x specifically regulates the interaction of MDC1 (mediator of DNA damage checkpoint protein 1), a DNA repair protein to the sites of DNA damage.
