Anti-Cytokeratin 18 Antibody

Offered through the Antibodies.com catalogue, this affinity-purified reagent is a polyclonal antiserum raised in rabbit against Cytokeratin 18, an intermediate filament protein widely used as an epithelial and hepatocyte marker. The unconjugated antibody is supplied as a 50 µl liquid formulation in PBS containing 50% glycerol, 0.5% BSA and 0.02% sodium azide, at a working concentration of 1 mg/mL, and is purified from rabbit antiserum by epitope-specific affinity chromatography. Validated application coverage includes Western blot (WB), immunohistochemistry (IHC), immunoprecipitation (IP), immunofluorescence (IF) and ELISA, making the reagent suitable for multi-assay workflows in epithelial cell biology and oncology research. The antibody shows reactivity with human, mouse and rat samples, and the rabbit IgG host isotype supports low-background detection across standard secondary antibody systems. For handling, the product is shipped at 4 °C and should be aliquoted and stored at -20 °C, with repeated freeze/thaw cycles avoided to preserve activity. Researchers studying cytoskeletal organisation, epithelial-mesenchymal transitions, or liver and gut pathology will find this lot a versatile primary reagent for both validation and discovery work.
