Product Summary for Cytokeratin 18 Antibody (KRT18/835)

Immunogen

Recombinant full-length human Cytokeratin 18 protein (Uniprot: P05783)

Reactivity Notes

Does not react with Rat, Sheep, Hamster, Bovine, Canine or Porcine.

Localization

Cytoplasmic

Specificity

This monoclonal antibody 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.

Applications for Cytokeratin 18 Antibody (KRT18/835)

Application
Recommended Usage

Immunohistochemistry-Paraffin

1-2 ug/ml

Western Blot

1-2 ug/ml
Application Notes
Immunohistochemistry (Formalin-fixed): 1-2ug/ml for 30 min at RT. Staining of formalin-fixed tissues requires heating tissue sections in 10mM Tris with 1mM EDTA, pH 9.0, for 45 min at 95C followed by cooling at RT for 20 minutes.
Optimal dilution for a specific application should be determined.
Please Note: Optimal dilutions of this antibody should be experimentally determined.
