Anti-CK17 Antibody

CK17 (Cytokeratin 17) is a type I intermediate filament protein of approximately 48 kDa, expressed in basal and myoepithelial cells of stratified and pseudostratified epithelia. This unconjugated mouse monoclonal reagent from Antibodies.com is supplied at 100 µl and is validated for Western blot, immunohistochemistry, and immunoprecipitation workflows on human samples. In research settings, CK17 serves as a marker for basal-like phenotypes in triple-negative breast cancer, squamous differentiation in head and neck tumors, and regenerative keratinocyte populations in skin and hair follicle studies. The antibody is reactive with human CK17 and is commonly applied to formalin-fixed paraffin-embedded tissue sections as well as to cell lysates for protein-level confirmation of epithelial lineage. Storage at 4 °C in single-use aliquots preserves activity across repeat experiments; protect from light and avoid repeated freeze-thaw cycles to maintain binding performance.
