Anti-Histone Macro H2A1 antibodies are protein reagents that detect specific antigens. The Histone Macro H2A1 antigen is another term for the human protein macroH2A.1 histone, encoded by the MACROH2A1 gene. The protein is known to function in DNA repair and the response to oxidative stress, among other biological roles. Canonically, it has an amino acid length of 369 residues and a mass of 39.2 kilodaltons. Its subcellular localization is in the nucleus and it is widely expressed across many tissue types. The Histone Macro H2A1 protein is a member of the Histone H2A protein family. Other alias names for Histone Macro H2A1 include H2A.y, H2A/y, and H2AF12M. Indicated applications for Histone Macro H2A1 antibodies listed below include ELISA, Western Blot, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry.
