Anti-H2B.2 antibodies enable researchers to detect and measure the H2B.2 antigen in biological samples. This target is a reported synonym of the H2BC17 gene, which encodes H2B clustered histone 17. This protein is an important component of nucleosome. The human version of H2B.2 has a canonical amino acid length of 126 residues and a protein mass of 13.9 kilodaltons. It is reported to be localized in the nucleus and chromosomes of cells and widely expressed in many tissue types. Other names for this target antigen include H2B/n and H2BFN.
