Cytokeratin 18 Antibody Cocktail

• Catalog Number: orb2638781
• Category: Antibodies
• Description: This mAb reacts with a wide variety of simple epithelia. It does not react with stratified squamous epithelia. It reacts with epithelial tumors of the gastrointestinal tract, lung, breast, pancreas, ovary, and thyroid. Cytokeratin 18, which belongs to the type A (acidic) subfamily of low molecular weight keratins, exists in combination with cytokeratin 8. It is reported that tissues from gastrointestinal tract are positive for both cytokeratin 8 and 18 but do not contain cytokeratin 14. Tissues from gastrointestinal tract, respiratory tract and urogenital tract, as well as endocrine and exocrine tissues and mesothelial cells are positive for cytokeratin 18.
• Clonality: Monoclonal
• Species/Host: Mouse
• Isotype: Mouse IgG1, kappa
• Conjugation: Unconjugated
• Reactivity: Human
• Buffer/Preservatives: 0.2 mg/ml in 1X PBS with 0.1 mg/ml rAlbumin (US sourced) and 0.05% sodium azide

• Immunogen: Recombinant full-length human KRT18 protein was used as the immunogen for the Cytokeratin 18 antibody cocktail.
• UniProt ID: P05783
• Tested applications: FACS, IHC-P, WB
• Dilution range: Flow Cytometry: 1-2ug/million cells in 0.1ml,Western blot: 1-2ug/ml,Immunohistochemistry (FFPE): 1-2ug/ml for 30 min at RT (1),Prediluted IHC only format: incubate for 30 min at RT (2)
• Application notes: Optimal dilution of the Cytokeratin 18 antibody cocktail should be determined by the researcher.1. Staining of formalin-fixed tissues requires boiling tissue sections in pH 9 10mM Tris with 1mM EDTA for 10-20 min followed by cooling at RT for 20 min2. The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.
