The synthetic peptide sequence is conjugated to KLH. The immunogen sequence is highly conserved (single amino acid substitution) in mouse histone H2AX.
synthetic phosphorylated peptide corresponding to the C-terminus (amino acids 134-142) of human histone H2AX (pSer139).
Histones (H1, H2B, H2A, H3 and H4) regulate the packaging of eukaryotic DNA into repeating nucleosome units that are folded in higher-order chromatin fibers 1. Phosphorylation of serine 139 in the histone H2AX subtype is induced by double-stranded breaks in DNA. H2AX histone has also been implicated in DNA repair mechanisms following double-strand breaks 2. Anti-phospho-Histone H2AX [pSer139] binds to histone H2AX phosphorylated on Ser139 (γ-H2AX) by immunoblotting (15 kDa). Staining of [pSer139] histone H2AX in immunoblotting is specifically inhibited with the [pSer139] histone H2AX immunizing peptide (human, amino acids 134-142). No inhibition is observed with the respective non-phosphorylated histone H2AX peptide (human, amino acids 134-142). The antibody product is also reactive in mice.
Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.
Anti-phospho-Histone H2AX (p(Ser139M)) antibody is suitable for use in western blot (1:1,000 using whole cell extracts of HeLa (human epitheloid carcinoma) cells or NIH3T3 mouse fibroblast cells treated with staurosporine) and microarray. The antibody may also be used in immunoblot assays.
