Anti-TMEM19 antibodies are used in the immunodetection of the protein transmembrane protein 19. In humans, the canonical protein has a reported length of 336 amino acid residues and a mass of 36.4 kDa. Its subcellular localization is in the membrane. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. It is a member of the TMEM19 protein family. TMEM19 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some TMEM19 antibodies may have been used in research and have associated citations. ELISA, Western Blot, and Immunohistochemistry are common applications for these antibodies.
