CLDN18 ELISA kits are immunoassay tools for the measurement of the protein claudin 18, which is encoded by the CLDN18 gene in humans. Functionally, 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. It is known to be localized in the cell membrane. As many as 2 protein isoforms have been reported. Other alias names for this target include SFTPJ, surfactant associated 5, surfactant associated protein J, surfactant, pulmonary associated protein J, and SFTA5.
There are CLDN18 ELISA kits that can detect a target at concentrations as low as 30 ng/L and as high as 20 ng/mL. Click on the products below for more detailed ELISA kit information, such as target reactivity and assay sensitivity.
