Anti-KRT19 Antibody [Assigned #A10948]

KRT19, also called cytokeratin 19, is a type I intermediate filament protein of approximately 40 kDa expressed in simple and stratified epithelia. This unconjugated rabbit IgG monoclonal reagent from Antibodies.com is raised against the KRT19 target and validated for western blot, immunohistochemistry, and immunofluorescence on human and mouse samples. In research settings the antibody is used to label ductal and glandular epithelium, profile circulating tumor cells in peripheral blood, and assist differential diagnosis between cholangiocarcinoma and hepatocellular carcinoma in liver tumor sections. Provided as 100 µl of liquid antibody, the format accommodates multiple staining runs and works with both chromogenic IHC and fluorescence imaging workflows.
