Further Information

Application Note:
Flow Cytometry: 0.5-1 ug/million cells in 0.1ml

Immunofluorescence: 1-2 ug/ml

Western blot: 0.5-1 ug/ml

Immunohistochemistry (FFPE): 0.5-1 ug/ml for 30 min at RT (1)

Prediluted format: incubate for 30 min at RT (2)

Optimal dilution of the Cytokeratin 8 + 18 antibody should be determined by the researcher.

1. Staining of formalin-fixed tissues requires boiling tissue sections in 10mM Citrate buffer, pH 6.0, for 10-20 min followed by cooling at RT for 20 min.
2. 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.

Background:
Cytokeratin 8 (CK8) belongs to the type II (or B or basic) subfamily of high molecular weight cytokeratins and exists in combination with cytokeratin 18 (CK18). This mAb recognizes all simple epithelia including glandular epithelium, for example thyroid, female breast, gastrointestinal tract, respiratory tract, and urogenital tract including transitional epithelium. All adenocarcinomas and most squamous carcinomas are positive but keratinizing squamous carcinomas are usually negative. This antibody is useful in demonstrating the presence of Paget cells; there is very little keratin 18 in the normal epidermis so only Paget cells are stained.
Buffer:
PBS with 0.1 mg/ml BSA and 0.05% sodium azide
