Anti-CLDN7 antibodies are used in the immunodetection of the protein claudin 7. In humans, the canonical protein has a reported length of 211 amino acid residues and a mass of 22.4 kDa. Its subcellular localization is in the cell membrane. Up to 2 different isoforms have been reported for this protein. It is reported to be expressed in the kidney, lung and prostate. A member of the Claudin protein family, CLDN7 is known to play an important role in tight junction-specific obliteration of the intercellular space. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include CPETRL2, Hs.84359, clostridium perfringens enterotoxin receptor-like 2, epididymis secretory sperm binding protein, and CEPTRL2. CLDN7 gene orthologs have been reported in the mouse, rat, bovine, frog and chimpanzee species. Over 110 citations in the literature describe the use of CLDN7 antibodies in research. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
