Anti-Cytokeratin 20 Antibody

Manufactured by Antibodies.com, this recombinant rabbit monoclonal reagent is directed against Cytokeratin 20 (KRT20), a type I intermediate filament protein that serves as a widely used marker of gastrointestinal epithelium and is frequently applied in studies of colorectal and pancreatic adenocarcinomas. The antibody is supplied as a 50 µl vial of an unconjugated, ready-to-use formulation in 1× TBS (pH 7.4) supplemented with 1% BSA, 40% glycerol, and 0.05% sodium azide as preservative, which allows convenient short-term storage at 2–8 °C and longer-term storage at -20 °C in aliquots to preserve activity. Cloned from a rabbit host and expressed recombinantly, the immunoglobulin is of the IgG isotype and is offered as a monoclonal preparation, ensuring batch-to-batch consistency and reproducibility in demanding research workflows. The reagent has been validated for a broad panel of applications, including Western blot (WB), immunocytochemistry and immunofluorescence (ICC/IF), immunohistochemistry (IHC), immunoprecipitation (IP), and flow cytometry (FC), making it a versatile choice for laboratories that need a single reagent across multiple readouts. Reactivity has been confirmed on human and rat samples, supporting its use in cell-line studies, primary tissue analysis, and relevant rodent disease models. Combined with the consistent quality associated with the Antibodies.com catalogue, this Anti-Cytokeratin 20 antibody provides a reliable tool for epithelial marker profiling, tumor characterization, and downstream signaling or differentiation studies.
