Biochem/physiol Actions

Cytokeratin facilitates the typing of normal, metaplastic, and neoplastic cells and may aid in the discrimination of carcinomas and non-epithelial tumors such as sarcomas, lymphomas, and neural tumors. It is also useful in detecting micrometastases in lymph nodes and other tissues, and for determining the origin of poorly differentiated tumors.

General description

Monoclonal Anti-Pan Cytokeratin (mouse IgG1 isotype) is derived from the PCK-26 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice immunized with a cytokeratin preparation from human epidermis. Cytokeratins are a group of at least 29 different proteins. They are characteristic of epithelial and trichocytic cells. Cytokeratin peptide 1 (68 kDa) is expressed together with cytokeratin 10 in the suprabasal cell layers or the differentiation compartment of the epidermis. Its expression increases with epidermal maturation and is modified post translationally in terminally differentiated keratinocytes of the stratum corneum. Cytokeratin peptide 5 (58 kDa) is the primary type II keratin in stratified epithelia, while cytokeratin type 8 (52 kDa) is a major type II keratin in simple epithelia. Cytokeratin 6 (56 kDa) is a "hyperproliferation" cytokeratin expressed in tissues with natural or pathological high turnover. Monoclonal antibodies to cytokeratins are specific markers of epithelial cell differentiation and have been widely used as tools in tumor identification and classification.

Immunogen

cytokeratin from human epidermis.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Specificity

The antibody recognizes an epitope located on the Type II cytokeratins 1, 5, 6, and 8. PCK-26 is a broad spectrum antibody which reacts specifically with a variety of normal, reactive, and neoplastic epithelial tissues. The antibody reacts with simple, cornifying, and non-cornifying squamous epithelia and pseudostratified epithelia.
