Anti-KRT20 Antibody [Assigned #A11401]

Cytokeratin 20 (KRT20) is a type I intermediate filament protein expressed primarily in gastrointestinal epithelium, urothelium, and Merkel cells, where it serves as a marker of epithelial differentiation and tumor origin. This unconjugated rabbit monoclonal IgG reagent is supplied by Antibodies.com as a 50 µl liquid aliquot in a single-use vial and is validated for western blot, immunohistochemistry, immunofluorescence, and immunoprecipitation workflows. Clonal production delivers reproducible epitope recognition across batches, supporting studies of colorectal carcinoma cell lines and Merkel cell biology. The antibody reacts with human and rat KRT20, enabling cross-species translational research. Store refrigerated and avoid repeated freeze-thaw cycles to preserve binding activity. For research use only.
