Monoclonal Mouse Anti-Human
Cytokeratin 7
Clone OV-TL 12/30
Reacts with the 54 kDa protein corresponding to cytokeratin 7.
The antibody labels several types of normal and neoplastic epithelia, including many ductal and glandular epithelia. Clone OV-TL 12/30 has been found useful for the identification of adenocarcinomas of the lung, breast and endometrium, thyroid gland and ovary, as well as chromophobe renal cell carcinomas. Antibodies to cytokeratin 7 may also be useful in the differential diagnosis of prostate carcinomas where CK7 is rarely expressed.

Breast lobular (FFPE) stained with FLEX Anti-Cytokeratin 7, Code IR619/IS619.
Breast lobular carcinoma. The majority of the neoplastic cells show a distinct and predominantly cytoplasmic, but also membrane accentuated staining reaction.
Clinical application for IR619/IS619. For identification of tumors of unknown origins and for staining of cytokeratin 7 in glandular and transitional epithelial cells appearing in various tumors.
Disclaimer: Due to variances among color computer monitors, the colors you see on your screen may not be the exact colors of the stain. The image you see should be considered close renditions to the actual stain.
- Optimized staining performance of both high- and low-expression structures
- Crisp and clear staining with no background
- Optimal laboratory efficiency with ready-to-use antibodies on Dako Autostainer Link 48
FLEX Monoclonal Mouse Anti-Human Cytokeratin 7, Clone OV-TL 12/30, Ready-to-Use (Link), is intended for use in immunohistochemistry together with Autostainer Link instruments. This antibody labels glandular and transitional epithelial cells and is useful for the identification of adenocarcinomas of the lung (1), breast and endometrium, thyroid gland (2) and ovary (3), as well as chromophobe renal cell carcinomas (4). 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 qualified pathologist.
Clone: OV-TL 12/30 (1). Isotype: IgG1, kappa.
