Relevance
Cytokeratins, a group comprising at least 29 different proteins, are characteristic of epithelial and trichocytic cells. Cytokeratins 1, 4, 5, 6, and 8 are members of the type II neutral to basic subfamily. Monoclonal anti cytokeratins are specific markers of epithelial cell differentiation and have been widely used as tools in tumor identification and classification. Monoclonal Anti Pan Cytokeratin （mixture） is a broadly reactive reagent, which recognizes epitopes present in most human epithelial tissues. It facilitates typing of normal, metaplastic and neoplastic cells. Synergy between the various components results in staining amplification. This enables identification of cells, which would otherwise be stained only marginally. The mixture may aid in the discrimination of carcinomas and nonepithelial tumors such as sarcomas, lymphomas and neural tumors. It is also useful in detecting micrometastases in lymph nodes, bone marrow and other tissues and for determining the origin of poorly differentiated tumors. There are two types of cytokeratins the acidic type I cytokeratins and the basic or neutral type II cytokeratins. Cytokeratins are usually found in pairs comprising a type I cytokeratin and a type II cytokeratin. Usually the type II cytokeratins are 8kD larger than their type I counterparts.

Immunohistochemistry （Formalin/PFA-fixed paraffin-embedded sections） - pan Cytokeratin antibody [PCK-26] （ab6401）
ab6401 staining pan Cytokeratin in Mouse liver tumor tissue sections by IHC-P （Paraformaldehyde fixed paraffin embedded sections）. Tissue was fixed with paraformaldehyde and blocked with maleate buffer blocking solution for 30 minutes and 22°C. Antigen retrieval was by heat mediation in citrate buffer. Samples were incubated with primary antibody （1/500） in maleate buffer blocking solution for 16 hours at 22°C. An undiluted biotin-conjugated Donkey polyclonal to mouse IgG was used as secondary antibody.

ab6401 staining pan Cytokeratin in mouse pancreatic ductal adenocarcinoma （left-hand panel） and mouse pancreatic neoplasia （right-hand panel） sections by immunohistochemistry （IHC-P - paraformaldehyde-fixed, paraffin-embedded sections）. Tissue samples were fixed with paraformaldehyde and blocked with 10% serum for 1 hour at room temperature; heat mediated antigen retrieval was performed. The sample was incubated with primary antibody （1/250） at 4°C for 8 hours. A Biotin-conjugated Goat polyclonal （1/1000） was used as the secondary antibody.
