Anti-CLDN11 antibodies are used in the immunodetection of the protein claudin 11. In humans, the canonical protein has a reported length of 207 amino acid residues and a mass of 22 kDa. Its subcellular localization is in the cell membrane. It is notably expressed in many tissues, such as the duodenum and skin. A member of the Claudin protein family, CLDN11 is known to play an important role in tight junction-specific obliteration of the intercellular space, through calcium-independent cell-adhesion activity. CLDN11 is also used as a cellular marker for characterizing oligodendrocytes. Synonyms for this target antigen include OSP, OTM, oligodendrocyte transmembrane protein, oligodendrocyte-specific protein, and HLD22. CLDN11 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 90 citations in the literature describe the use of CLDN11 antibodies in research. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
