Anti-Keratin 18 Antibody

A polyclonal antibody targeting the intermediate filament protein Keratin 18, supplied by Antibodies.com as a 100 µl aliquot of unconjugated rabbit antiserum. Keratin 18 is a type I cytokeratin expressed in simple epithelia of the liver, pancreas, gastrointestinal tract, and glandular tissues, making this reagent useful for distinguishing epithelial-origin tumors in immunohistochemistry and immunofluorescence workflows. Validated for western blot, IHC, and IF, the antibody reacts with human samples and supports studies of epithelial differentiation, carcinoma classification, and apoptosis research using caspase-cleaved K18 fragments. The unconjugated format allows flexible pairing with secondary antibodies labeled to a researcher's preferred fluorophore or enzyme. Intended for research use only.
