Validation Data Gallery

Filter:
  • Western Blot (WB) analysis of various lysates using Phospho-Histone H2A.X (Ser139) Recombinant antibod (83307-2-RR)

    WB analysis using 83307-2-RR (same clone as 83307-2-PBS)

    Non-treated Jurkat cells, and staurosporine treated Jurkat cells were subjected to SDS PAGE followed by western blot with 83307-2-RR (Phospho-Histone H2A.X (Ser139) antibody) at dilution of 1:10000 incubated at room temperature for 1.5 hours. The membrane was stripped and re-blotted with Alpha Tubulin (66031-1-Ig) antibody as loading control. This data was developed using the same antibody clone with 83307-2-PBS in a different storage buffer formulation.

  • Immunohistochemistry (IHC) staining of Jurkat cells using Phospho-Histone H2A.X (Ser139) Recombinant antibod (83307-2-RR)

    IHC staining of Jurkat using 83307-2-RR (same clone as 83307-2-PBS)

    Immunohistochemical analysis of paraffin-embedded Jurkat cells slide using 83307-2-RR (Phospho-Histone H2A.X (Ser139) antibody) at dilution of 1:4000 (under 40x lens). Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0). This data was developed using the same antibody clone with 83307-2-PBS in a different storage buffer formulation.

  • Immunofluorescence (IF) / fluorescent staining of HeLa cells using Phospho-Histone H2A.X (Ser139) Recombinant antibod (83307-2-RR)

    IF Staining of HeLa using 83307-2-RR (same clone as 83307-2-PBS)

    Immunofluorescent analysis of (4% PFA) fixed UV treated HeLa cells using Phospho-Histone H2A.X (Ser139) antibody (83307-2-RR, Clone: 5N19 ) at dilution of 1:400 and CoraLite®488-Conjugated Goat Anti-Rabbit IgG(H+L) (SA00013-2), CL594-Phalloidin (red). This data was developed using the same antibody clone with 83307-2-PBS in a different storage buffer formulation.

Background Information

The histone variant H2AX is a major component of the DNA damage response (DDR), especially functioning in amplifying DNA damage signals. In response to DNA double-strand breaks (DSBs), H2AX is instantaneously phosphorylated at Ser139 (a form called cH2AX) by the kinases ATM and ATR. The phosphorylation of H2AX at Ser139, resulting in the formation of gamma-H2AX puncta in the nuclei, is an early event in the cellular response to DNA damage. Therefore, phospho-Histone H2A. X (Ser139) is also known as γH2AX. The phosphorylation site of H2AX, Ser139, has also been described as Ser140 in other literature, and they recognize the same amino acid site.
