Claudin-4 (EP417) Rabbit Monoclonal Primary Antibody
Specialties: Cytopathology Pulmonary Pathology
The claudin-family proteins are a group of tight-junction membranous proteins responsible for paracellular molecular flow between adjacent cells of the epithelium.1 In normal kidney, claudin-4 plays a key role in paracellular ion reabsorption.2 Claudin-4 is expressed in most epithelial cells yet is absent in mesothelial cells, making it of great use in characterizing epithelial malignincies.3 Immunohistochemical identification of this antigen may help identify poorly differentiated lung adenocarcinoma from lesions of mesothelial origin.4 Likewise, identification of claudin-4 expression by IHC may be useful in characterizing breast and endometrial lesions.5,6
