Anti-ISX antibodies are used in the immunodetection of the protein intestine specific homeobox. In humans, the canonical protein has a reported length of 245 amino acid residues and a mass of 27 kDa. Its subcellular localization is in the nucleus. ISX is reported to be a transcription factor that regulates gene expression in intestine. Synonyms for this target antigen include RAX-like homeobox and pancreas-intestine homeodomain transcription factor. ISX gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some ISX antibodies may have been used in research and have associated citations. Immunofluorescence is a widely used application for these antibodies. Western Blot, Immunocytochemistry, and Immunohistochemistry are also common applications.
