Anti-PRSS8 Antibody

PRSS8 (prostasin) is a glycosylphosphatidylinositol-anchored serine protease expressed on the apical surface of epithelial cells, where it participates in regulating sodium channel activity, epithelial barrier function, and protease-activated receptor signaling. The Antibodies.com polyclonal reagent is raised in rabbit and supplied at 1 mg/ml in phosphate buffered saline with 15 mM sodium azide at approximately pH 7.2. This unconjugated IgG is validated for Western blot detection of human, mouse, and rat PRSS8, supporting comparative studies of epithelial ion transport, skin barrier biology, and tumor contexts where altered prostasin expression has been reported. Each vial contains 100 µl of the antibody preparation, and the azide-containing formulation is compatible with standard immunoblotting workflows using HRP- or fluorophore-conjugated secondary reagents. For storage, refrigerate the vial and protect from light to preserve antibody activity.
