Anti-TM4SF5 antibodies are used in the immunodetection of the protein transmembrane 4 L six family member 5. In humans, the canonical protein has a reported length of 197 amino acid residues and a mass of 20.8 kDa. Its subcellular localization is in the lysosomes and cell membrane. A member of the L6 tetraspanin protein family, TM4SF5 is known to act as a lysosomal membrane arginine sensor. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include tetraspan transmembrane protein L6H, transmembrane 4 superfamily member 5, and transmembrane 4 L6 family member 5. TM4SF5 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. ELISA is a widely used application for the TM4SF5 antibodies listed below. In addition, Flow Cytometry is also a common application.
