Anti-Cytokeratin 8 Antibody

Cytokeratin 8 is a type II intermediate filament protein abundantly expressed in simple and glandular epithelia, where it contributes to cytoskeletal integrity and serves as a widely used epithelial lineage marker. This polyclonal reagent from Antibodies.com is raised in rabbit and supplied unconjugated at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol, packaged as a 50 µl vial sized for pilot experiments and small staining panels. Validated uses include western blot, immunohistochemistry, immunocytochemistry, and immunofluorescence, and the antibody has been confirmed to react with Human, Mouse, and Rat samples, supporting epithelial cell and tissue studies across these species. For routine handling, store refrigerated at 4 °C for short-term use or freeze at -20 °C in single-use aliquots to limit freeze-thaw cycles and preserve binding activity; the included sodium azide preservative inhibits microbial growth in the working solution. Intended for research use only.
