Alternate Names for gamma H2AX [p Ser139] Antibody (2F3)

  • H2A histone family, member X
  • H2A.X
  • H2a/x
  • H2AX histone
  • H2AXhistone H2A.x
  • YH2AX


H2A.X is a 14 kD basal histone and a member of the H2 histone family. This nuclear protein is synthesized in the G1 and S phase of the cell cycle and is known to be important for recombination between immunoglobulin switch regions. H2A.X becomes phosphorylated on serine 139 after double-stranded DNA breaks. Phosphorylated H2A.X promotes DNA repair and maintains genomic stability. The 2F3 monoclonal antibody reacts with phosphorylated human H2A.X (Ser139) and has been shown to be useful for Western blotting and immunofluorescence.
