Anti-Histone H2AX Antibody [Assigned #A0823]

Histone H2AX is a chromatin-associated histone variant that becomes rapidly phosphorylated at Ser139 (γH2AX) at sites flanking DNA double-strand breaks, making antibodies against this target a standard tool for tracking DNA damage and repair responses. This unconjugated mouse monoclonal reagent from Antibodies.com (clone #A0823, IgG isotype) detects human Histone H2AX in western blot and immunohistochemistry workflows, supporting studies in radiation biology, genotoxicity screening, and cancer research where DSB formation and resolution are being monitored. Supplied as 200 µl of liquid antibody, it enables nuclear staining patterns on fixed tissue sections and consistent band detection on immunoblots when paired with appropriate HRP- or fluorophore-conjugated secondary antibodies.
