Anti-Cytokeratin 20 Antibody, clone IT-Ks20.8

General description

IT-Ks 20.8 represents an excellent marker for certain types of carcinomas such as adenocarcinomas of the colon, transitional cell carcinomas of the bladder and Merkel cell tumors of the skin. Very sensitive detection of intestinal and gastric foveolar epithelium, urothelial umbrella cells, Merkel cells of epidermis as well as tumors originating therefrom (e.g. primary and metastatic colorectal carcinoma). Adenocarcinomas of breast, lung, endometrium and ovary (non-mucinous) as well as neuroendocrine tumors of the lung are essentially negative.

Specificity

The antibody is specific for the 46 kDa polypeptide (cytokeratin 20).

Immunogen

Electrophoretically purified cytokeratin 20 from human intestinal mucosa

Application

Western blotting
Immunohistochemistry: 1:10 dilution of stock on frozen tissues, with one hour incubation at room temp or overnight at 2°-8°C. For paraffin sections, 1:100 dilution of antibody with protease pretreatment and/or heat induced epitope retrieval recommended.
Cytological material

Studies of cultured cell lines HT-29, LoVo, DLD-1, SW1116, CaCo-2 & RT-4.

Optimal working dilutions must be determined by the end user.
