Cytokeratins are a subfamily of intermediate filaments and characterized by remarkable biochemical diversity. Cytokeratins are represented in epithelial tissues by at least 20 different polypeptides, molecular weight between 40 kDa and 68 kDa. The individual cytokeratin polypeptides are designated 1 to 20 and divided into the type I (acidic cytokeratins 9-20) and type II (basic to neutral cytokeratins 1-8) families.
Cytokeratins 10 and 13 both belong to type I family (acidic cytokeratins).


The antibody DE-K13 reacts with Cytokeratin 10 (56.5 kDa) and Cytokeratin 13 (53 kDa). Cytokeratins are a member of intermediate filaments subfamily represented in epithelial tissues. DE-K13 recognizes only Cytokeratin 13 on formalin-fixed, paraffin-embedded tissue sections.
