WebThis Sandwich ELISA kit is an in vitro enzyme-linked immunosorbent assay for the measurement of human phospho-gamma H2A.X. An anti-pan gamma H2A.X antibody has been coated onto a 96-well plate. Samples are pipetted into the wells and gamma H2A.X present in a sample is bound to the wells by the immobilized antibody. H2A histone family member X (usually abbreviated as H2AX) is a type of histone protein from the H2A family encoded by the H2AFX gene. An important phosphorylated form is γH2AX (S139), which forms when double-strand breaks appear. In humans and other eukaryotes, the DNA is wrapped around histone octamers, consisting of core histones H2A, H2B, H3 and H4, to form chromatin. H2AX contributes to nucleosome-formation, chr…
