W16171A_A647_H2AX_Antibody_1_110119
HeLa cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with Triton X-100 for 10 minutes, and blocked with 5% FBS for 60 minutes. Cells were then intracellularly stained with 1 µg/mL (1:500 dilution) of either Alexa Fluor® 647 Rat IgG2a, κ Isotype Ctrl Antibody (Cat. No. 400526, panel A) or Alexa Fluor® 647 anti-H2A.X antibody (panel B) overnight at 4°C. Nuclei were counterstained with DAPI and the image was captured with a 60X objective.

Description

Histone subunit H2A, along with subunits 2B, 3, and 4, make up the core subunits of the nucleosome octomer. An octomer contains two protomers of each subunit tightly wrapped around a ~147 bp segment of DNA. Histones have integral roles in chromatin integrity, genomic stability, and gene regulation. Post-translational modification of histones in response to certain stimuli results in alterations of nucleosomal positioning relative to DNA. Histone H2A.X is a non-allelic variant of Histone 2A that harbors a C-terminal extension and is essential for checkpoint mediated cell cycle arrest and DNA double-stranded break (DSB) repair in response to both endogenous and exogenous agents, as well as meiotic recombination events and immunoglobulin class switching in lymphocytes. Phosphorylation of C-terminal residue serine 139 by ATM (γ-H2A.X) results in the recruitment of DSB-repair machinery. Phopshorylation of H2A.X is also critical for chromatin fragmentation during apoptosis.

Application Notes

This product is a monoclonal antibody raised against the C-terminus of H2A.X (residues 127-143); BioLegend’s existing antibody against H2A.X (Poly6133, cat# 613302) is a polyclonal antibody which was generated against (partial), N-terminal H2A.X.

This clone is not recommended for ChIP (Chromatin Immunoprecipitation) assays (as determined by in-house testing).
