Listed are ELISA Kits for the detection of MacroH2A, an alias name of H2A histone family member Y. The human protein, encoded by the gene H2AFY, is 372 amino acid residues long and has a mass of 39,617 daltons. However, there are up to 3 reported isoforms. This protein is reported to have a nuclear cellular localization. This target may also be known as: core histone macro-H2A.1, histone H2A.y, histone macroH2A1, histone macroH2A1.1, medulloblastoma antigen MU-MB-50.205, H2A.y, and H2A/y.
