Anti-KRT4 Antibody - Identical to Abcam (ab197385)

KRT4 (Keratin 4) is a type II intermediate filament protein expressed in mucosal and stratified squamous epithelia, including the oral cavity, esophagus, and corneal surface. Antibodies.com offers this rabbit polyclonal antibody for Western blot detection of endogenous KRT4 in human, mouse, and rat samples. The reagent is supplied as an unconjugated IgG in 200 µl, allowing flexible pairing with HRP- or fluorophore-conjugated secondary antibodies. Research groups working on epithelial differentiation, mucosal barrier function, and disorders linked to KRT4 such as White Sponge Nevus use this antibody to characterize keratin filament expression in cell lysates and tissue extracts. The polyclonal format provides multi-epitope recognition, supporting consistent band identification across experimental preparations and reducing the risk of signal loss caused by single-epitope variation.
