Anti-KRT18 Antibody [Assigned #A0389]

Keratin 18 (KRT18) is a 48 kDa type I intermediate filament protein expressed in epithelial tissues and is widely used in research as a marker of epithelial cell identity and of circulating tumor cells of epithelial origin. This Mouse monoclonal IgG antibody from Antibodies.com, assigned clone A0389, is supplied as a 50 µl liquid aliquot of unconjugated reagent.

Validated for Western blotting (WB) and immunocytochemistry (ICC), the antibody binds human and non-human primate (monkey) samples, supporting translational epithelial-biology research, hepatocyte and intestinal-epithelial studies, and tumor cell characterization. In WB workflows it is used to detect the characteristic ~48 kDa KRT18 band in whole-cell lysates, while in ICC it labels the intermediate filament network in cultured epithelial cells.

Working aliquots should be stored refrigerated at 4 °C to preserve activity and avoid repeated freeze-thaw cycles. Each lot is quality-controlled, and the unconjugated format allows direct pairing with a secondary antibody chosen for the user's preferred detection chemistry, providing flexibility across imaging and immunoblotting pipelines.
