Anti-CLDN4 Antibody

Produced by Antibodies.com, this rabbit polyclonal IgG reagent targets claudin-4, a tetraspan membrane tight junction protein that seals paracellular gaps in epithelial sheets and is implicated in pancreatic, ovarian, and gastric tumor biology as well as mucosal barrier dysfunction. The unconjugated antibody is supplied as 100 µl of stock and validated for Western blot and immunohistochemistry on human and mouse specimens, recognizing multiple epitopes on the approximately 22 kDa target for reproducible band detection on blots and clean membrane staining in tissue sections.

Aliquot on arrival and store frozen at -20°C, avoiding repeated freeze-thaw cycles to preserve binding activity. The polyclonal format is well suited for epitope redundancy across denatured and native preparations, and is intended for research use only rather than clinical or diagnostic work.
