CLDN19 ELISA kits are immunoassay tools for the measurement of the protein claudin 19, which is encoded by the CLDN19 gene in humans. Functionally, this protein is known to play an important role in tight junction-specific obliteration of the intercellular space, through calcium-independent cell-adhesion activity. The canonical protein structure is reported to have an amino acid length of 224 residues, a mass of 23.2 kDa, and is a member of the Claudin protein family. It is known to be localized in the cell membrane. As many as 3 protein isoforms have been reported. The CLDN19 gene has been associated with the disease, Hypomagnesemia.
Some CLDN19 ELISA kits can detect targets at levels as low as 20 ng/L and as high as 10 ng/mL. Click on the products below for more detailed ELISA kit information, such as target reactivity and assay sensitivity.
