Anti-KRT4 Antibody - Identical to Abcam (ab197385)

KRT4 (Keratin 4) is a type II cytokeratin expressed predominantly in mucosal stratified squamous epithelia, including the oral cavity, esophagus, and tongue. This polyclonal reagent from Antibodies.com is raised in rabbit and supplied as an unconjugated IgG preparation in a 100 µl volume, suitable for Western blot detection of endogenous KRT4 in human, mouse, and rat samples.

The antibody binds to the target keratin and is validated for Western blot workflows, supporting studies of epithelial differentiation, mucosal integrity, and keratin network biology. Mutations in KRT4 are associated with white sponge nevus, an autosomal dominant disorder of the oral mucosa, so reliable detection of this cytokeratin is relevant for research into stratified epithelial pathology and tissue-specific keratin expression.

Provided as 100 µl of affinity-purified polyclonal antibody, the reagent is intended for laboratory research use and supports cross-species reactivity profiling across commonly used mammalian model systems.
