Pan Cytokeratin Antibody Cocktail

Immunohistochemistry (FFPE): 1-2ug/ml

Optimal dilution of the recombinant Pan Cytokeratin antibody should be determined by the researcher.

PCK/4933R demonstrates a broad spectrum of cytokeratin reactivity. In normal tissues, PCK/4933R is reactive with most epithelial types, including bile ducts and hepatocytes in liver, bladder epithelium, breast ducts, bronchial epithelium, endometrium, intestinal epithelium of stomach, duodenum, ileum, colon, rectum, pancreas, ovarian epithelium, pancreatic acini, pituitary acini, pneumocytes, prostate, thyroid, skin (positive on the basal layer and negative on the superficial layers of squamous epithelium), and apocrine and sweat glands. In tumors, PCK/4933R is reactive with most carcinomas, including breast, transitional cell (TCC), renal cell (RCC), lung adenocarcinoma, lung small cell, lung squamous cell, endometrial, prostate, ovarian, hepatocellular (HCC), colorectal CA, stomach and thyroid. It is negative in certain normal tissues, including brain, lymphocytes and all cells of hematolymphoid origin, muscle, brain, nerves, endothelium and in certain tumors including most melanomas, sarcomas, lymphomas, primitive neuroectodermal tumors (PNET)/Ewings and gastrointestinal stromal tumors (GIST). Positivity has been seen on some dendritic cells in lymph nodes, some endothelia, and some muscle cells.

Crude cytokeratin extract prepared from RT-4 and MCF-7 cells was used as the immunogen for the recombinant Pan Cytokeratin antibody.

This recombinant Pan Cytokeratin antibody is available for research use only.
