Phospho histone
WebBecause phosphorylation of H2AX at Ser 139 (γ-H2AX) is abundant, fast, and correlates well with each DSB, it is the most sensitive marker that can be used to examine the DNA damage produced and the subsequent repair of the DNA lesion. γ-H2AX can be detected by immunoblotting and immunostaining using microscopic or flow cytometric detection. WebHistone H2A.X (H2AX) is a member of the histone H2A family which is one of the four core histones making up the nucleosome core particle. In eukaryotes, DNA double strand breaks (DSBs) have been shown to trigger the phosphorylation of serine 139 at the carboxy terminus of histone H2AX resulting in gamma-H2AX.

WebHistone H2A.X is considered a basal histone, being synthesized in G1 as well as in S-phase, and its mRNA contains polyA addition motifs and a polyA tail along with the conserved stem-loop and U7 binding sequences involved in the processing and stability of replication type histone mRNAs. WebHistone H3 is one of the five main histones involved in the structure of chromatin in eukaryotic cells. [1] [2] Featuring a main globular domain and a long N-terminal tail, H3 is …
WebHuman Phospho-Histone H2AX (S139) Antibody Summary Species Reactivity Human Specificity Detects human Histone H2AX when phosphorylated at S139. Source Polyclonal Rabbit IgG Purification Antigen and protein A Affinity-purified Immunogen Phosphopeptide containing human Histone H2AX S139 site Formulation H2AX becomes phosphorylated on serine 139, then called γH2AX, as a reaction on DNA double-strand breaks (DSB). The kinases of the PI3-family (Ataxia telangiectasia mutated, ATR and DNA-PKcs) are responsible for this phosphorylation, especially ATM. The modification can happen accidentally during replication fork collapse or in the response to ionizing radiation but also during controlled physiological processes such as V(D)J recombination. γH2AX is a sensitive target for …
