Anti-Cytokeratin 19 Antibody

Manufactured by Antibodies.com, this affinity-purified rabbit polyclonal reagent is raised against Cytokeratin 19 and is supplied as a 50 µL liquid formulation at 1 mg/mL in PBS containing 50% glycerol, 0.5% BSA and 0.02% sodium azide. The immunogen is a synthesized peptide derived from the internal region of human Cytokeratin 19, and the antibody specifically detects endogenous levels of the Cytokeratin 19 protein. It is unconjugated and validated for use across a broad panel of applications including ELISA, Western blot (WB), immunocytochemistry/immunofluorescence (ICC/IF) and immunohistochemistry (IHC). The reagent shows reactivity with Human, Mouse and Rat samples, making it a versatile choice for cross-species cytokeratin research, including studies of epithelial markers and hepatocyte identity. Routine handling is straightforward: the antibody is shipped at 4 °C and should be aliquoted upon arrival and stored at –20 °C, with repeated freeze/thaw cycles avoided to preserve performance. Each lot is affinity-purified from rabbit antiserum by affinity-chromatography using an epitope-specific immunogen, supporting low background and consistent signal in demanding applications. This product is intended for research use only and is not suitable for diagnostic or therapeutic applications.
