Introduction
In eukaryotes, including humans, DNA is tightly wound around histone groups. H2AX is a member of the core group of histones that contributes to nucleosome formation and DNA structure. When a DNA double-strand break is introduced into the genome, the H2AX histones near the break are phosphorylated by the ATM kinase at residue Ser-139. Upon phosphorylation H2AX is referred to as gamma-H2AX. Given that only H2AX histones near the site of DNA damage are phosphorylated, γH2AX is a useful target when determining the abundance and location of double-strand breaks.
In your γH2AX assay experiment, you will assess the effects of ...
