Anti-Histone H2A.v antibodies enable researchers to detect and measure the Histone H2A.v antigen in biological samples. This target is a reported synonym of the H2AZ2 gene, which encodes H2A.Z variant histone 2. The human version of Histone H2A.v has a canonical amino acid length of 128 residues and a protein mass of 13.5 kilodaltons, although 5 isoforms have been identified. It is reported to be localized in the nucleus and chromosomes of cells and widely expressed in many tissue types. Histone H2A.v is a member of the Histone H2A protein family.
