The following Claudin 18 ELISA kits are useful research tools for the measurement of claudin 18 in biological samples. In humans this protein is encoded by the CLDN18 gene. This protein is known to be involved in alveolar fluid homeostasis via regulation of alveolar epithelial tight junction composition and therefore ion transport and solute permeability, potentially via downstream regulation of the actin cytoskeleton organization and beta-2-adrenergic signaling (By similarity). The canonical protein structure is reported to have an amino acid length of 261 residues, a mass of 27.9 kDa, and is a member of the Claudin protein family. Its subcellular location is known to be in the cell membrane. As many as 2 protein isoforms have been reported. This protein may also be known as SFTPJ, surfactant associated 5, surfactant associated protein J, surfactant, pulmonary associated protein J, and SFTA5.
Some Claudin 18 ELISA kits can detect targets at levels as low as 30 ng/L and as high as 10 ng/mL. Use the search filters to narrow your search and click on the ELISA kits below for more detailed information, such as reactivity and assay sensitivity.
