Description

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 cocktail 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.Immunohistochemical staining with this MAb is indistinguishable from that obtained with monoclonal antibody 5D3.

Application Notes

Optimal dilution of the recombinant CK8/18 antibody should be determined by the researcher.

Immunogen

Recombinant full-length human CK8 and CK18 proteins were used as the immunogen for the recombinant CK8/18 antibody.

Storage

Aliquot the recombinant CK8/18 antibody and store frozen at -20oC or colder. Avoid repeated freeze-thaw cycles.
