Background information

Histone H2A is one of the 5 main histone proteins involved in the structure of chromatin in eukaryotic cells. Featuring a main globular domain and a long N terminal tail H2A is involved with the structure of the nucleosomes of the 'beads on a string' structure.

Physical form

Purified rabbit polyclonal IgG in buffer containing 0.1 M Tris-glycine, pH 7.4, 0.15 M NaCl, 0.05% sodium azide before the addition of glycerol to 30%.


A previous lot of this antibody successfully immunoprecipitated phosphorylated H2A.X as determined by an independent laboratory.


Histone H2A.X phosphorylated at Ser139.


KLH-conjugated, synthetic peptide (CKATQA[pS]QEY) corresponding to amino acids 134-142 of human histone H2A.X. The immunizing sequence has 8 identical amino acids in yeast and mouse.

Species Reactivity Notes

Human; broad species cross-reactivity expected based on conservation of sequence homology.

Quality Assurance

Routinely evaluated by Western Blot on untreated and staurosporine treated Jurkat lysate.

Western Blot Analysis:
1:500 dilution of this lot detected phospho-H2A.X on 10 μg of staurosporine treated Jurkat lysate.
