Cytokeratin 7 Antibody (Immunohistochemistry)

The Cytokeratin 7 (CK7) Antibody is a widely used immunohistochemical marker.
It helps distinguish epithelial-origin tumors derived from various tissues.
In addition, CK7 is a basic cytokeratin expressed in glandular and transitional epithelia such as
the lung, breast, uterus, and urothelium. However, it is typically absent in stratified squamous and
colorectal epithelium.

Moreover, CK7 becomes even more informative when paired with CK20.
As a result, the CK7/CK20 profile provides a reliable diagnostic pattern for differentiating lung, breast,
ovarian, and endometrial carcinomas from colorectal and prostate carcinomas.
Therefore, CK7 is essential in routine tumor classification.

🔬 Features and Benefits

• Specific marker for glandular and urothelial epithelial tumors
• Clear brown cytoplasmic staining in positive cells
• Useful for identifying lung, breast, and endometrial carcinomas
• Compatible with standard IHC diagnostic procedures
• Stable for up to 18 months at 2–8 °C

💡 Diagnostic Applications

• Detection of lung and breast adenocarcinomas
• Evaluation of endometrial and urothelial carcinomas
• Differentiation from colorectal and prostate carcinomas when used with CK20
• Research on epithelial differentiation and tumor origin
