Anti-Claudin-9 Antibody

This rabbit polyclonal reagent from Antibodies.com targets the tight junction transmembrane protein Claudin-9, one of the claudin family members that seal the paracellular space between adjacent epithelial cells. Supplied as 100 µl of antibody at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol, it is validated for Western Blot detection of the human, mouse, and rat Claudin-9 orthologs. Glycerol-containing aliquots should be stored at -20 °C to preserve antibody activity across multiple freeze-thaw cycles, with small working stocks kept refrigerated to limit handling losses. The unconjugated format lets researchers pair it with their own HRP, fluorescent, or biotin secondary antibodies for chemiluminescent or imaging workflows, and the polyclonal antibody pool covers multiple epitopes across the Claudin-9 sequence for downstream tasks such as membrane fraction characterization and expression profiling in epithelial and inner ear tissue models.
