Anti-KRT19 Antibody [Assigned #A10948]

KRT19 (Keratin 19, also called Cytokeratin 19) is a type I intermediate filament protein expressed in epithelial cells. This unconjugated rabbit monoclonal antibody from Antibodies.com recognizes the KRT19 target and is validated for western blot, immunohistochemistry, and immunofluorescence workflows. It cross-reacts with both human and mouse samples, making it a versatile reagent for studies of epithelial lineage, ductal differentiation, and carcinoma cell biology. The reagent is supplied as 50 µl of liquid IgG and is suited to labeling cytokeratin networks in fixed tissue sections and cultured epithelial cells. Researchers commonly apply it to characterize circulating tumor cells, mammary and gastrointestinal epithelium, and cholangiocyte-like progenitors, where KRT19 serves as a reliable epithelial marker distinct from mesenchymal markers such as vimentin.
