Anti-Claudin-19 Antibody

Claudin-19 is a transmembrane tight junction protein with documented roles in renal and ocular epithelial biology, and mutations in the CLDN19 gene are linked to familial hypomagnesemia with hypercalciuria and nephrocalcinosis (FHHNC). The Antibodies.com Anti-Claudin-19 Antibody is a rabbit polyclonal reagent raised against this target for research studies of epithelial barrier function and ion transport.

Supplied as 100 µl of unconjugated polyclonal antibody, this reagent is validated for Western blot (WB) and ELISA workflows and has been characterized for reactivity against human and rat Claudin-19. The unconjugated format is compatible with common detection strategies, including chemiluminescent Western blot and standard ELISA plate-based assays, and pairs with the researcher's choice of labeled secondary antibodies.

For handling, keep the liquid antibody refrigerated and aliquot upon arrival to limit freeze-thaw cycles, preserving activity across multiple experiments. The reagent is intended for research use only.
