Anti-KRT19 Antibody

Sourced from Antibodies.com, this affinity-purified reagent is a rabbit polyclonal antibody raised against a recombinant human KRT19 immunogen and validated for use in western blotting (WB) and immunohistochemistry (IHC). The antibody detects the endogenous total KRT19 protein and is supplied as an unconjugated preparation at 1.0 mg/mL in a 50 µL volume, formulated in phosphate-buffered saline (pH 7.4, 150 mM NaCl) containing 0.02% sodium azide and 50% glycerol as a cryoprotectant. The host species is rabbit, the clonality is polyclonal, and the target corresponds to Keratin-19, also known as CK-19, K19, KRT19, Cytokeratin-19, or Keratin type I cytoskeletal 19. Reactivity has been confirmed in Human, Mouse, and Rat samples, making the reagent broadly useful across rodent and human model systems. 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. As a primary antibody listed under the Antibodies.com Primary Antibodies category, it is intended for research use only and is not validated or intended for diagnostic or therapeutic applications. The combination of affinity purification, defined formulation, and clean WB/IHC validation makes this Anti-KRT19 reagent a practical choice for laboratories studying epithelial and hepatocellular markers, where cytokeratin 19 expression is commonly monitored.
