Anti-TSPAN19 antibodies are used in the immunodetection of the protein tetraspanin 19. In humans, the canonical protein has a reported length of 248 amino acid residues and a mass of 28.5 kDa. Its subcellular localization is in the membrane. It is a member of the Tetraspanin (TM4SF) protein family. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include putative tetraspanin-19. TSPAN19 gene orthologs have been reported in the bovine, chimpanzee and chicken species. Indicated applications for TSPAN19 antibodies listed below include Immunohistochemistry.
