This assay produces membranous staining.

The transmembrane Claudin 18 proteins comprise a major component of tight junctions, which regulate paracellular barrier permeability and membrane polarity. CLDNs control the selective transport of ions across cells and maintain the integrity of epithelial and endothelial layers.^1,2 In mammals, 27 Claudin family members have been identified.³ The predicted protein structure of CLDN includes four transmembrane segments⁴ with two extracellular loops, and the N- and C- termini localized in the cytoplasm. Claudin 18 gene is a 785-base pair cDNA coding for a 261 amino acid protein of ~27.7 kDa molecular weight. Claudin 18 has two isoforms (CLDN18.1 and 18.2). CLDN18.2 differs from CLDN18.1 in the N-terminal 69 amino acids, including the first extracellular loop.⁵

Unlike most of the CLDN family members, CLDN18 does not exhibit broad tissue expression. Isoforms of CLDN18 can be detected short-lived in differentiated epithelial cells of the normal gastric mucosa and pneumocytes in normal lung tissue, in a variety of advanced and metastatic gastrointestinal cancers, including gastric, esophageal, pancreatic, biliary duct cancers, and in non-small-cell lung cancer.^6-12
