Anti-Keratin 8 Antibody

Manufactured by Antibodies.com and distributed through AFMS, this affinity-purified reagent is a rabbit polyclonal antibody raised against Keratin 8, designed to detect endogenous levels of the total Keratin 8 protein in research applications. The antibody is provided as a 50 µL aliquot at a working concentration of 1.0 mg/mL and is supplied in a formulation of Rabbit IgG in phosphate-buffered saline (without Mg²⁺ and Ca²⁺) at pH 7.4, containing 150 mM NaCl, 0.02% sodium azide, and 50% glycerol as a cryoprotectant. The product is unconjugated, allowing users freedom in selecting their own secondary detection reagents, and has been validated for use in Western blot (WB) and immunohistochemistry (IHC) workflows. It demonstrates cross-reactivity across three commonly studied species, recognizing Keratin 8 in human, mouse, and rat samples. The immunogen is a synthesized peptide derived from human Keratin 8, and the antibody is polyclonal, meaning the reagent pool contains a diverse range of epitope-specific immunoglobulins. For optimal stability, the product is shipped at 4 °C; upon receipt, users are advised to aliquot the antibody and store it at –20 °C, taking care to avoid repeated freeze/thaw cycles that can degrade immunoglobulin performance. As supplied, this reagent is intended strictly for research use and is not validated for diagnostic or therapeutic applications.
