Anti-Keratin 20 Antibody

Supplied by Antibodies.com as a rabbit polyclonal reagent, this affinity-purified antibody targets total Keratin 20 and is validated for Western blot (WB) and immunohistochemistry (IHC) workflows. The immunogen is a synthetic peptide derived from human Keratin 20, and the antibody was purified from rabbit antiserum by affinity-chromatography using the epitope-specific immunogen, ensuring recognition of endogenous levels of the target protein. The reagent is offered in a 50 µl volume at a concentration of 1 mg/ml, formulated in rabbit IgG in phosphate-buffered saline (without Mg²⁺ and Ca²⁺), pH 7.4, containing 150 mM NaCl, 0.02% sodium azide, and 50% glycerol. It is unconjugated and shipped for storage at –20 °C. Cross-reactivity has been confirmed in human, mouse, and rat samples, making it suitable for studies across these species. The product is supplied by AFMS and is intended for research use only, not for diagnostic or therapeutic applications. Researchers working on epithelial differentiation, gastrointestinal tract markers, urothelial carcinomas, or Merkel cell biology will find this polyclonal reagent a reliable choice for detecting Keratin 20 in cell and tissue lysates by WB and in formalin-fixed paraffin-embedded sections by IHC.
