Q-STAIN X (QSXTM)-Enh Anti-Human CK7 antibody is intended for laboratory use to qualitatively identify by light microscopy the presence of CK7 in sections of formalin-fixed, paraffin-embedded tissue sections or frozen tissues using immunohistochemistry (IHC) test methods. The clinical interpretation of any staining or its absence should be complemented by morphological studies using proper controls and should be evaluated within the context of the patient’s clinical history and other diagnostic tests by a
Summary and Explanation:
QSX-Enh CK7 is a ready-to-use rabbit monoclonal antibody reagent (Clone R284). CK7 is filament protein of 55 kD molecular weight within the cytokeratin family. Clone R284 antibody reacts with cytokeratin 7 which is found in simple glandular epithelium, and in transitional epithelium. Cytokeratin 7 is expressed in the majority of cases of carcinoma, with exception of those carcinoma arising from the colon, prostate, kidney, and thymus; carcinoid tumors of the lung and gastrointestinal tract origin; Merkel cell tumor of the skin.
