Anti-Claudin-9 Antibody

Rabbit polyclonal antibody reagent specific for Claudin-9, distributed by Antibodies.com as 100 µl at 1 mg/ml in PBS buffer at approximately pH 7.9 with 0.05% sodium azide preservative. Recommended for western blot workflows probing lysates from human, mouse, or rat samples, the unconjugated antibody targets the four-transmembrane tight-junction protein that contributes to epithelial barrier integrity, auditory hair-cell function in the cochlea, and tight-junction remodeling reported in select cancer studies. The polyclonal format allows recognition of multiple epitopes across the ~23 kDa target in denatured samples, making it a practical option for researchers characterizing claudin expression across tissues and disease models.
