The Phospho-Histone H2AX-S139 Monoclonal Antibody (CABP0687) is a high-quality antibody developed for reliable detection and analysis of target proteins. This antibody specifically targets the phosphorylated form of histone H2AX at serine 139, a marker of double-strand DNA breaks.Phosphorylation of H2AX at serine 139 is a key event in the cellular response to DNA damage, triggering a cascade of events that recruit repair factors to the site of damage. This antibody, raised in rabbits, is highly sensitive and specific for detecting phosphorylated H2AX in various cell types and is validated for use in Western blot and immunofluorescence applications.
This antibody is validated for use in WB, IHC-P, IF/ICC, ELISA applications and has demonstrated reactivity against Human, Mouse, Rat samples.

Histones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Two molecules of each of the four core histones (H2A, H2B, H3, and H4) form an octamer, around which approximately 146 bp of DNA is wrapped in repeating units, called nucleosomes. The linker histone, H1, interacts with linker DNA between nucleosomes and functions in the compaction of chromatin into higher order structures. This gene encodes a replication-independent histone that is a member of the histone H2A family, and generates two transcripts through the use of the conserved stem-loop termination motif, and the polyA addition motif.
