General description

Histone H2AX (H2A histone family member X), a histone variant present in almost all eukaryotes, is coded by H2AFX gene. It is mapped to human chromosome 11q23.2–11q23.3.


This antibody reacts to Histone H2A.X only when phosphorylated at serine 139. No cross reactivity with other phosphorylated histones.


Synthetic peptide corresponding to Phospho-Histone H2AX (Ser139)

Physical form

Solution in phosphate buffered saline containing 50% glycerol, 1% BSA and 0.09% sodium azide.

Biochem/physiol Actions

H2AX (H2A histone family member X) helps to maintain genome stability. It plays an important role in localisation and structuring of the repair focus. H2AX also plays an active role in supplying the active repair proteins. γH2AX participates in DSB repair. This protein serves as a signal and target of phosphorylation in the spreading phase.
