Anti-Nanog homeobox antibodies are used for the immunodetection of the protein encoded by the NANOG gene. In humans, the canonical protein has a reported length of 305 amino acid residues and a mass of 34.6 kDa. Its subcellular localization is in the nucleus. Alternative splicing is reported to yield 2 different isoforms for this protein. It is reported to be expressed in testicular carcinoma and derived germ cell tumors. A member of the Nanog homeobox protein family, it is known to be a transcription regulator involved in inner cell mass and embryonic stem (ES) cells proliferation and self-renewal. Other names for this target antigen include homeobox transcription factor Nanog, homeobox transcription factor Nanog-delta 48, and homeobox protein NANOG. Gene orthologs have been identified in the mouse, rat, bovine and chimpanzee species. Over 2100 citations in the literature describe the use of Nanog homeobox antibodies in research. Western Blot is a widely used application for these antibodies. ELISA, Flow Cytometry, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
