Anti-Keratin 18 Antibody

Offered by Antibodies.com, this affinity-purified reagent is a Rabbit polyclonal antibody raised against human Keratin 18 (KRT18), an intermediate filament protein widely used as an epithelial marker. The antibody was generated using a synthesized peptide immunogen derived from the human target and detects endogenous levels of total Keratin 18 protein. It is supplied as a 50 µL aliquot at 1.0 mg/mL in a PBS buffer (pH 7.4) containing 150 mM NaCl, 0.02% sodium azide and 50% glycerol, with no fluorophore or enzyme label — the conjugate is unconjugated. The host is Rabbit, the clonality is polyclonal, and the isotype is IgG. Validated applications include Western blot (WB), immunohistochemistry (IHC) and immunocytochemistry/immunofluorescence (ICC/IF), with reactivity confirmed against human samples. For handling, the product is shipped at 4°C and should be aliquoted and stored at −20°C upon arrival; repeated freeze/thaw cycles should be avoided to preserve antibody activity. Suitable for epithelial and cytoskeletal research, epithelial-mesenchymal transition studies, and biomarker characterization in cell biology and pathology workflows.
