Anti-KCTD19 antibodies are used in the immunodetection of the protein potassium channel tetramerization domain containing 19. In humans, the canonical protein has a reported length of 926 amino acid residues and a mass of 104.9 kDa. KCTD19 is known to be involved with protein oligomerization. Synonyms for this target antigen include potassium channel tetramerisation domain containing 19, potassium channel tetramerization domain-containing protein 19, testicular tissue protein Li 101, and BTB/POZ domain-containing protein KCTD19. KCTD19 gene orthologs have been reported in the mouse, rat, bovine, chimpanzee and chicken species. Some Kctd19 antibodies may have been used in research and have associated citations. Immunofluorescence is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
