Anti-Cytokeratin 20 Antibody

Raised in rabbit against the intermediate filament protein Cytokeratin 20, this polyclonal reagent from Antibodies.com is supplied as an unconjugated preparation in a 100 µl vial format. The antibody recognizes the human target and shows reactivity in mouse and rat samples, supporting translational studies across species. Recommended applications include Western blot, immunohistochemistry, immunofluorescence, and ELISA workflows, allowing labs to move from tissue localization to protein-level detection with the same reagent. Cytokeratin 20 is widely used by pathology researchers as a marker of gastrointestinal, urothelial, and Merkel cell origin, making this antibody a practical tool for tumor phenotyping, differentiation studies, and epithelial cell characterization in both fixed and fresh specimens.
