Anti-SUZ12 antibodies are used in the immunodetection of the protein SUZ12 polycomb repressive complex 2 subunit. In humans, the canonical protein has a reported length of 739 amino acid residues and a mass of 83.1 kDa. Its subcellular localization is in the nucleus. It is notably expressed in breast and colon cancer. A member of the VEFS (VRN2-EMF2-FIS2-SU(Z)12) protein family, SUZ12 is known to be involved with cell proliferation and the regulation of cell differentiation. Post-translational modifications have been described, including sumoylation. Synonyms for this target antigen include IMMAS, JJAZ1, polycomb protein SUZ12, chET 9 protein, chromatin precipitated E2F target 9 protein, and CHET9. SUZ12 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 290 citations in the literature describe the use of SUZ12 antibodies in research. Western Blot is a widely used application for these antibodies. ELISA, Immunoprecipitation, and Immunohistochemistry are also common applications.
