Stains / Test Description
This antibody is directed against a type II cytokeratin protein expressed by most ductal, glandular and transitional epithelia. Cytokeratin 7 exhibits a cytoplasmic localization. This antibody may be used to aid in the identification of normal and neoplastic cells of ovary, lung and breast epithelial origin which express Cytokeratin 7, and those of colonic and prostate epithelial lineage which lack Cytokeratin 7 production.
