Histone H2AX is a core histone protein that is phosphorylated at S139 in cells exposed to DNA double-strand break-inducing agents, such as ionizing radiation. The S139 phosphorylated H2AX, termed gamma -H2AX, marks the site of DNA double-strand breaks and serves to recruit cell cycle checkpoint and DNA repair factors to the site of damage.

Detection of Human Histone H2AX by Western Blot.
Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line untreated (-) or treated (+) with 20 mJ/cm2 ultraviolet light (UV) followed by a 30 minute recover. PVDF membrane was probed with 0.25 µg/mL of Rabbit Anti-Human Phospho-Histone H2AX (S139) Monoclonal Antibody (Catalog # MAB2288) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (HAF008). A specific band was detected for Histone H2AX at approximately 17 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Detection of Human Phospho-Histone H2AX (S139) in Camptothecin-treated Jurkat cells by Flow Cytometry.
Naïve Jurkat cells (open histogram) or treated with 1 µM Camptothecin (1100, filled histogram) overnight were stained with Rabbit Anti-Human Phospho-Histone H2AX (S139) Monoclonal Antibody (Catalog # MAB2288), followed by PE-conjugated Anti-Rabbit IgG Secondary Antibody (F0110). To facilitate intracellular staining, cells were fixed with Flow Cytometry Fixation Buffer (FC004) and permeabilized with 90% methanol.
