Cytokeratin Antibodies / CK Antibodies

Cytokeratin Antibodies validated for IHC & WB. Explore CK Antibodies for epithelial biology, cancer diagnostics, and translational research.

Cytokeratin Antibodies Overview

Cytokeratin Antibodies target the cytokeratin (CK) family of intermediate filament proteins expressed in epithelial cells. Cytokeratins form part of the cytoskeleton, providing structural integrity, mechanical support, and protection against stress. There are more than 20 cytokeratin isoforms, typically expressed in tissue-specific patterns that reflect cell type, differentiation state, and disease status.

Cytokeratins are widely used as biomarkers in pathology. For example, CK7 and CK20 help distinguish between different carcinomas, while high-molecular-weight cytokeratins such as CK5/6 mark basal cells. The Cytokeratin Antibodies portfolio enables precise detection of these proteins, while CK Antibodies more broadly support studies in epithelial biology, oncology, and regenerative medicine.
